I don’t want to delete my truck so I can see smoke!!!!!!! What’s the point of that??? I, like everyone else want efficiency, reliability, and power. EGR and DPF are major detractors to that equation. I know Gale doesn’t agree with engines eating their own shit (EGR), but he must tip toe with the EPA. But it should be acknowledged that 98% of people wanting to delete are NOT doing so just to see smoke!

[@dougn6465]

Agree 100%. People dont delete to roll coal. They delete for the massive power and fuel mileage gains.

[@evernhamanderson]

I was talking to a Cummins Mech. this weekend. He claims 95% of all issues they see with modern engines can be tracked back to the EGR system. He says deletes fix nearly all issues with diesel engines.

[@Karjis]

@@evernhamanderson yeah and EGR delete does not need DPF delete so it doesn't even add smoke, things just work with DPF delete. As far to usability only downside of EGR delete is slightly slower heating after cold start but that is not an issue in most locations and seems not to bother all engines. By my experience that issue can be helped by restricting airflow to engine bay during winter months. It also prevents some corrosion for the radiator / IC during salty times. No point of having enough airflow to survive in +120F if outside air is close to 0F

[@MrSkyentist]

A lot of the focus is around the dpf. Here's a valid question: Why do manufacturers make these components welded to the exhaust vs having crush seals with clamps so they can be quickly and easily changed out when they do go bad? To normal people, it's rare enough to not be an enormous deal, but when a person uses it as a work vehicle, it can reach the end of its life in three years time. By the time a vehicle reaches 150-200k miles, it's typically devalued to the point it's not cost effective to spend the cash to replace it. So then people buy new vehicles. Sounds like a large carbon footprint to mine, refine, stamp, and manufacture all of the components of a new vehicle no? Next is the egr (my large gripe). It soot loads the intake and combined with oil from the pcv, it completely gums up everything in the intake. It also soot loads the oil meaning accelerated component wear for any moving part in the engine. Though egr does reduce NOX emissions, whats the trade off here? Suddenly it takes million mile engineering down to 300k. SCR and plastic jugs are another irritating item. If every diesel pump had def nozzles, it wouldn't be as big of a deal but single use plastic jugs are garbage. I'd keep the exhaust crap to keep the epa happy but the egr choking up the entire system is horrible. Higher egr rates also lead to more black smoke production, clogging the dpf faster leading to more frequent regens. I know gale banks is a brilliant individual in the tuning world, with nearly unparalleled knowledge, but I would like to see him take some stance on what should be acceptable vs too far when it comes to emissions restrictions. Hes got more knowledge on the subject than probably every consultant for CARB and the EPA combined.

[@hpa101]

I think it depends on the vehicle. It seems to be more common that you can clean a filter instead of just replacing it - Taz.

[@DrifterDavid]

I have to agree with you MrSkyentist and also the fact that a lot of these items reduce fuel mileage which just pollutes even more. But why make an essentially non-serviceable part for the average joe and something that is thousands of dollars and an absolute pain in the ass to replace. Granted I know this isn't ever vehicle. But it does make things frustrating. And myself being in auto repair industry. When you get a car back in that is stuck in regen mode or clogged up. Do you think that dealership is going to replace all those parts to make it function as normal again or patch it up enough to get it on the lot and working for 5k miles so the customer can cover the cost. I guarantee its gonna be the latter.....so in another few thousand miles gonna be in the same boat again if you don't buy extended warranty. Which lot of times is a rip-off anyways.

[@revell7156]

As an major domestic certified dealer technician i can promise you OE manufacturers do not care about you (directly), or the ease of a vehicles repair. They care about sales and profit margins. If they can assemble a vehicle faster by having one huge exhaust component they will. It reduces part numbers (build materials) and time to install. Vehicles are built and engineered to be assembled on a mechanical assembly line. Whatever makes that job easier is what they care about. It's easier to pay us flag hour techs in the dealership to repair or replace something later than it is to slow down or stop an assembly line. They don't care about me, you, or anything else. As long as the vehicle is sold and can make it out of warranty, they're good. Also, the engineered lifetime of a vehicle is 150k miles. Lifetime fluids, lifetime filters, etc all are 150k mile services, or until a catastrophic failure, obviously.

[@immikeurnot]

@@hpa101 On almost all (the vast vast majority) of light and medium duty trucks, the DPF is at the very least part of a welded assembly with the DOC. They can be cleaned, but the weld between the two has to be cut, and then the assembly has to be rewelded afterwards. It's just idiotic engineering from the OEMs pushed our way by the idiots in the government.

[@Biggordon01]

I have alot of respect for banks, he has developed the systems that comply with the epa garbage, while at the same time improving the power. However I would say no matter how good the emissions on tuning is, I would never tune the engine with the emissions on to add more power. I would not want to exercise the dpf/egr any more than it already is, or have to service the system sooner. I realize that the air/fuel ratio remains the same to where there is no smoke, but it would still make a higher quantity of soot even though A/F ratio remains the same. It will never be better than emissions off tuning. Period. Ive went from 11 mpg to 19 mpg meanwhile not having to worry about the emmisions systems failing. Win-Win in my book.

[@VJ-ft2xj]

Diesel emissions are bull$hit. Diesel engines hardly ever fail. What fails- dpf, egr cooler, intake clogged with soot from egr, etc. Make these devices last 500k miles routinely, no one would complain. Dpfs go out all the time, and they take out the engine with them. Modern delete tunes increase reliability, longevity, and often double the fuel mileage of the truck. It has nothing to do with blowing smoke.

@@hpa101 Why are people making glider 2020 semi trucks with older Cummins, Caterpillar, and Detroit engines? No one wants to be stranded in the middle of the nowhere in limp mode/ derate. Diesels thrive with 2 things air and fuel that's basic stoichiometry. In small engine applications whether it be cummins, duramax, or powerstroke the turbos restrict the engine on purpose to keep egts higher and egrs cleaner. The mess of oil dilution, cylinder wash down, cracked heads, and turbo failure follows suit. Emissions are a joke and there are valid reasons for removal such as high sulfur diesel, racing, gliders, and reliability. But of course someone with a new diesel engine ought to know they are buying into a whole suit of problems when the sensors go haywire.

[@Garth2011]

There is no good for the individual owner. The cost of the vehicle, the cost of poor fuel mileage, the cost of DEF, the cost of added maintenance and the cost of mechanical failures due to emission equipment designed for the dinosaur era all mean less value to the owners. It seems the EPA is good with the extra cost per individual to get the overall results in emissions at no cost factor limits. No business could survive that business model. These soot and NOx controls are archaic devices that cost a fortune to maintain/use. I say if you don't really need a diesel buy a gasoline engine and forget about giving up tens of thousands to the vehicle makers and the subcontractors who are failing BIG in the emission controls. Just look as the gasoline engines of today...they have more power and torque than the older muscle car engines that polluted big in the 60's yet way less pollution due to engineering within the induction systems and controlling fuel more precisely. They haven't spent enough engineering time on the diesel so this is the jalopy idea they are using for now.

For my situation, with the ‘12 lml, I’m not so concerned with more hp and torque, nor rolling coal. My concern is engine life, performance (in getting the most out of a ounce of fuel), and reliability of components.

[@davidriley7411]

The replies to this video show a certain lack of understanding of the subject at hand so I thought I'd add a (lengthy) reply of my own to explain some things. A diesel particulate filter (DPF) doesn't require diesel emission fluid (DEF) to work. DEF is for nitrogen oxide (NOx) reduction. DEF is a mixture of urea and water. Urea is made of oxygen, nitrogen and hydrogen. In the selective catalyst (SCR) urea becomes ammonia which reacts with NOx to become water and nitrogen. Diesels produce lots of NOx because of their high temperature combustion. A gas engine alternates between rich and lean. When it is lean the catalytic converter cleans up hydrocarbons and carbon monoxide by turning them into water and CO2 . When it is rich it cleans up NOx by turning it into nitrogen and oxygen or in other words air. The catalytic converter in a gas engine is actually two converters in one. The two parts only work well when conditions are right. Specifically, the converter that cleans NOx doesn't work well unless there is almost no oxygen in the exhaust (rich mixture). Since a diesel is never rich, the catalyst is not efficient in cleaning up carbon monoxide (CO). To overcome this problem DEF is added to the SCR to make the converter more effective in handling the NOx. DEF helps the SCR to do a better job of reducing NOx in the presence of oxygen. EGR is used to reduce the amount of NOx made in the first place by reducing the temperature of combustion. Since exhaust won't burn, it's mass just absorbs heat from combustion and therefore reduces the temperature. Any inert gas or liquid added to the intake would do the same thing but exhaust does it well enough and is available and free. If the DEF and SCR worked well enough it wouldn't be necessary to have EGR and vice versa. Together, EGR, DEF and the SCR take care of NOx. A deleted truck produces a lot of NOx and there is little that can be done to tune it out. When the mixture gets richer than about 18:1, which is still way leaner than a gas engine's 14.7:1, the engine starts to produce much more soot. The hydrogen in the fuel burns first and the carbon uses what ever oxygen is left. Since diesels have very little time for fuel and air to mix it is necessary to have excess oxygen available to burn up all of the carbon. When race trucks and tractors blow all of that black smoke it is because they are sacrificing fuel efficiency and breathable air for power. Essentially they are throwing away a bunch of carbon in order to use as much hydrogen as possible. Hydrogen makes more power than carbon. The black soot in diesel exhaust isn't technically coal. It is more precisely called coke, which is coal minus the hydrogen that most coal contains or charcoal which is wood minus the hydrogen. So rolling coal is more correctly called rolling coke/charcoal. The size of diesel soot particles is tiny. It takes a very fine filter to remove a significant portion of it. It is a very big technical challenge to make a filter that can survive exhaust pipe temps and filter out the soot while not choking off the exhaust. Even a very clean diesel makes significant soot. One of the frontiers of diesel engine design for the last 150 years has been to clean up the exhaust while running as rich as possible. One way is to simply filter the soot out of the exhaust. Of course there is a limit to how much junk a filter can hold. With an air or oil filter we can simply change it often but with a DPF the cost of replacing it is too high to make that viable. The alternative is to clean the filter by burning off the soot from time to time. Soot has to be pretty hot to burn well. The catalytic converters create heat as they clean up the pollutants so by placing the DPF behind the converters it runs hot enough to burn off some of the soot during normal operation. That isn't sufficient though. Since there is always oxygen in the exhaust of a diesel there is the option to burn more fuel in the exhaust to make it even hotter to improve the oxidizing of the soot in the DPF. If the converter is doing its thing properly it will be running hot enough to ignite extra fuel injected into the exhaust. The exhaust will then be hot enough to clean the DPF. The DPF is often built into the catalytic converter to facilitate this. The cleaning of the DPF is called regenerating. It is wasteful of fuel but it makes having a DPF possible. When the carbon in the DPF combines with oxygen in the exhaust it makes CO2, and nothing else. The fuel injected into the converter burns cleanly so all the makes is water and CO2. The exhaust has more things in it than combustion gasses and soot. One thing it has is ash from additives in the oil. Oil gets into the combustion chamber from the crankcase ventilation system, past the rings , past the valve stem seals and past the turbo seals. There is always some dirt in the fuel. There is also dirt that gets past the air filter. This ash winds up in the DPF and can't be burnt out. Hence the need to eventually replace the DPF or get it purged of ash. If everything is working properly, what comes out of the exhaust of a diesel engine vehicle is nitrogen, oxygen, water and CO2. There will be minute traces of other things but those who care are generally satisfied by the result. It is easy to see why people would want to delete their trucks, given the problems we see today. The problem is, air pollution is a real thing. The first time I flew into LA was in 1972. As we arrived I looked down on the city below but but couldn't see the ground because of the very strange clouds When we landed I couldn't see across the airport because of the smog. I don't think anyone wants to go back to that.

[@davidriley7411]

Your write up of the diesel exhaust system is very good, but there are two things I would like to push back on. 1. The smog over LA has been around long before the first combustion engine. 2.

Once the nitrogen hits atmosphere it enters the nitrogen cycle.

Don’t think they would make it run that shit WOT on purpose.

I get why he’s saying this, he can’t sell illegal and always was emissions friendly products for the times. The problem is, there is no denying the data almost 2 decades of emissions controls on diesels has proven. The 6.0 EGR issues, the 6.4 early DPF trucks frying motors (the 6.7 Cummins had emissions gremlins too), and on the new ones the fluid is a nightmare. I have a 05 F350 long box CC 4x4 lariat, it has 285,000 miles on it, deleted EGR at 200,000 but all stick otherwise, and finally lost its head gaskets a few months ago. I studded it, put in the updated oil cooler and a 4 inch mbrp turbo back, it’s running fantastic and I fully expect to see 500,000 miles now from it, and I average 24 mpg on the highway, I drive slow lol but can’t beat it. My dad has had his 2008 F350 6.4 since brand new, deleted at 150,000, dpf and egr, 4 inch flow pro with muffler but no cat. That truck now has 234,000 not a single issue, with proper maintenance it should go a long way. We both use SCT x4 trans only emissions off tunes, neither truck rolls any coal, they run great. I have 3 friends with 2018-2019 trucks, one duramax, one powerstroke and one Cummins. Each and every one has been in for clogged DPF, regen issues. I’ve towed the dodge home with 700 miles on the clock because the spot filter sensor was too plugged up to command a regen. Two weeks ago my buddies powerstroke threw a rod towing his travel trailer and sled on the deck, no warning. I went and pulled his shit home with my 15 year old clunker and got better mpg to boot. All failures are emissions related. It’s crazy anyone can dance around the overwhelming evidence on this. The 6.4 goes from a driving time bomb to a good motor just by deleting that shit before you get too much blow by and oil dilution. The 6.0 once deleted and updated is one of the best diesels on the road. Emissions is garbage.

I got 475,000 on my deleted 07’ 6.0 1 ton Lariat. Im aiming for 1 million miles. Truck has held up great. I don’t roll coal or race it. I use it like a truck and spend good money maintaining it. The new 6.7s are nice but my 6.0 is so easy to work on and damn reliable.

[@xSPORTSMAN1993x]

Modern Diesel engines are very efficient and when properly tuned do not smoke. Adding dpf and def only increases the cost of the vehicle and vehicle ownership while reducing longevity. ie getting 12-14 mpg in a truck vs 18-22 mpg in a deleted truck. At what point does having slightly better emissions out weigh the substantial amount of extra fuel burned.

Throwing epa and dpf out for a moment, I have a question regarding diesels as I have very limited experience with modifying these as compared to gasoline engines. If all the black smoke from the tailpipe is representing unburned fuel what are the pros and cons to this? In the early tuner days all the big name brand tuners it seemed when installed would roll coal. I'm referring to the days of the late 7.3s, 6.0s, Duramaxes, etc up until the deletes became an issue. It seems to me, contrary to Banks, although I want to know, that these other companies aren't just stupid. So is the added fuel being used for a cooling effect or something else? And from the con perspective, and gasoline experience, wtf is this doing to piston rings and cylinder bores?

At the end of the day the guys at Calibrated Power & Banks Power have made it possible over these years to still be able to tune these trucks & gain hp as well.

Yes the emissions systems have their faults but over the years they haven't really been that bad. The company my Dad works for has a fleet of diesels and for the most part they've all been doing decent, in fact more of the trucks that do have problems aren't really emissions related. The 2005 Silverado 3500 HD is falling apart due to old age, the 2009 Silverado 3500 HD just has a ton of computer issues, the 2016 Sierra 3500 HD (which has 300k miles btw), the only emissions issue it's had is the DEF injector sensors getting melted preventing the truck from going into regen causing it to get plugged up with soot, (Truck Master has a great vid on this with his GMC as he had the same issue with it). Yeah it was not cheap to fix, but nothing on a diesel is most of the time. Since then it's been great with very minimal issues, the other truck is a 2019 F350 which they haven't had it for that long so it's too new to see how reliability will be on it. The point being is that any truck can have it's issues, some more than not. But as far as reliability with those systems if it's been properly maintained it will last a long time!!

At the end of the day, horsepower is a function of air and fuel delivery. My truck (6.4) with the DPF on is capable of maybe 400-450 RWHP safely. You could turn it up but it wouldn't be long before something blew. Take the DPF off and I can run a quarter mile in 12.9-13.1 seconds, which is about 650-670 RWHP considering the weight of the truck. Cats and DPFs create massive amounts of air restriction in the form of backpressure, which reduces power output and sends EGTs sky-high. I don't much care for smoke. I went with Gearhead tunes for that exact reason (clean tunes, 6.4s can be really smoky). The top end power is the same if not better than the box H&S tunes. However, I lost quite a bit of response on the bottom end (more lag). My buddy with a 6.7 noted the same thing.

Most of the Finnish diesel tuners are running old Mercs and Volvos. Of course the highly tuned precamber diesels produce tons off smoke but they say it is "power smoke" which sound really stupid :D

Removal due to replacement costs is a different kettle of fish compared to the goal of removal for tuning purposes. On this front, the aftermarket is catching up but some laws around replacement with aftermarket units will have to change as well in some locations to make an impact - kzbin.info/www/bejne/qKrLZaOfd9uDn7s Power smoke, I have not heard that one before 😂 I know the EU has done a u-turn on diesel vehicle usage so there are some interesting times ahead for you guys - Taz.

Zeihon kanava I have a 2012 320d, with around 320000km on the clock. It is still on the original DPF! If the car is serviced and driven as expected for regen cycles, it should last. I am a technical trainer; we find the main problem is that technicians don’t find the route cause for a DPF blocking in the first place, so just replace it - or suggest to delete it. There are so many issues that will affect the DPF regeneration, you really have to know the system well and have good diagnostic skills. For example, the ECU on a diesel can not detect an air leak up to 10mm!

@@MechanicMindset My daily is E46 320D with mildly tuned engine, better flowing intercooler and remap making around 210Hp/450NM. EGR is deleted but I am not sure is the DPF removed. No smoke until the redline when turbo stop being effience. In Finland average car age is 12 years and most of them are death traps full of sketchy duct tape and ziptie repairs just enough to pass MOT every year, so thats why DPF delete is so popular here. If it pass MOT you are good thats the main theme of owning car. :D

Banks is a god when it comes to making power and being efficient! Look and high hp imports they run super clean cause power comes from efficiency! Something diesel tuners dont do as well!

I would have loved for him to delve into the details of diesel being used to cool the charge to increase charge density. Yeah a lot of smoke comes out unburned but that doesn't mean it isn't doing something, it's using the latent heat of diesel gas to take heat out of the chamber since it takes so much energy to turn something from liquid to gas. I've mentioned this before, you see it in old F1 videos they call it "fluff", and diesel guys have told me that while some extra is definitely helpful, the huge amounts of smoke coming out of "rolling coal" is far beyond the useful amount of extra fuel. Because I don't know where that line gets crossed exactly it would have been nice if somebody as knowledgeable as Gale Banks would have let us know at what point is it totally wasted and how much is actually helpful instead of just saying we fully comply with all emissions blabla unless we're racing. People don't do rolling coal for no reason at all. It must have at least started as a way to increase power even if they go far beyond, but I really don't know, it's too bad Gale couldn't answer...

[@TheEsseboy]

It from tractor pulling where they run so much diesel to try and keep the turbocharger alive, it's stupid but less expensive than buying the 5000-10000 dollars of sensors and several hundred of dyno and calculation hours to get the EGT down and boost to backpressure under control.

[@hpa101]

@sirgallium We get emails from people asking how to teach them to make their exhaust produce 'AK47 noises'. Trust me, people 'roll coal' for no reason at all other than because they think it's fun to do so in a street application. That aside, your question has some merit, although Gale did make it clear that even in his racing applications the goal is 'clean' burning. I wouldn't go as far to state he couldn't answer the question though as he wasn't directly asked it. It's hard to cover everything on one topic in a single interview, but we will be back talking about this again in the future I have no doubt. I can't comment from my personal experience on The Esseboy's comment, but I wouldn't be surprised if there were truth to that. Many people put budget above performance - Taz.

[@El_Chompo]

@@hpa101 Sorry about your emails but that's hilarious. You make a good point about his goals being clean burning, and I didn't mean to imply that the question couldn't be asked, engines are an endlessly broad topic and I appreciate everything you did have the time to go over. I'm guessing that the useful upper limit is when there is so much extra fuel that the charge is oxygen deprived. And I wouldn't doubt rolling coal starting at tractor pulls partly for utility but also for spectacle.

[@bridged13b]

I believe rolling coal is basically used to get the turbo to spool. Excess fuel creates heat in a diesel, this helps the turbo spool. You'll notice that the soot will clear up when the engine comes up onto boost

[@El_Chompo]

@@hpa101 I was watching more Gal Banks and I just wanted to get back to you because I think I figured out the answer to my own question. The reason smoke is so associated with diesels tuned up to make more power is because since there is no throttle body you can initially make more power by just turning up the fuel. However at some point turning it up more will no longer create more power because you start to run out of oxygen. The amateurs don't really notice or care about this and just turn the pressure way up, and it gets them more power, so they're happy. I still don't fully understand the "fluff" qualifying F1 turbo tunes from the old days though. It must be for cooling, but then they turn the fuel back down so that they have enough fuel for a whole race whereas during qualifying it doesn't matter how inefficient it is. I looked up an old qualifying lap and you can see a pretty large cloud come out the back when they step on it, but it's not exactly smoke. It looks like a mix somewhere between vapor and smoke. But since a solvent fuel is so much different than an oil fuel I'm not sure how much you can really compare the exhaust gasses.

[@dougn6465]

Started with a banks turner on my 03. Switched to a smarty and the power was night and day difference. Smarty throws alot more smoke, unfortunately, but theres no denying the power difference between the 2 tunes. Gale's trying to keep the diesel industry on the right side of the law. Cant knock him for that.

Your mind would be blown by a correct tune from a reputable hptuner dealer.
