I worked for Cummins for 6 years. The second you get a 6.7 delete it and throw on an EGR blocker plate and APR head studs

[@quentonmillstid850]

Cummings employee is encouraging breaking the law. Engine so bad you have to commit a crime to make it decent

[@user-zb2os7xx1y]

i have a 2015 fully deleted but all the emissions still intact to the motor just unpluged no blocker plate. 4 inch straight pipe 5 inch exhaust tip. does not having the blocker plate on and all emissions still intact does it affect anything??

[@6.7ram]

Literally first thing I did along with a b.d trans.

[@monsterram6617]

Intake: The factory air box flow enough to support over 500 whp. If you're tuned/deleted you don't need an aftermarket one. Exhaust: Unless you're deleting the DPF/SCR, you're not changing exhaust. If you are there's not much difference between a 4" and 5" aside from the 5" is a pita to fit in there. Tuning: Avoid box tuners. Get a custom tune. Good luck. Gauges: You want to at least monitor EGTs. Trans temp is good but most truck have this on the dash already. Lift pump: The factory pump is fine until you add bigger injectors or CP3. Valve springs, HD push rods, head studs: If you are running more boost (40+) and higher RPM (3200+) then you need these. Otherwise save your money for the transmission. Transmission: Weird no one mentioned this... if you have a G56 get a Southbend or Valair clutch. If you have a 68rfe at least upgrade the valve body. If you have the Aisin, sorry there's not much that can be done. Gears: Ditch the 3.42s and go with 4.10s. If running big tires (37+s) go bigger on gears.

[@cass8144]

What’s wrong with tune boxes may I ask? Just curious

[@monsterram6617]

@@cass8144 Most will adjust fueling to where you see inefficient and sometimes unsafe IATs, EGTs, etc which give low power gains and can cause a head gasket to fail, or if emissions-on your DPF/SCR to clog/fail. The few that don't do this will net you limited gains as compared to a custom tune that has been either tested on many, many trucks before yours or one that is custom tailored for you from data logs. These type of tunes have to be flashed into the ECM. Examples are EfiLive, MM3, EzLynk. They are not a box that plugs into the OBII and "fools" the ECM; they rewrite an entire new tune into it and right now they are hard to find. Then there's the Bullydog which is kind of in between. It flashes your ECM and it's a box-like tuner. It provides many more tuning options for the end-user than many box tuners but if you don't know what you're doing you can break things. Not a bad option though if you have a 07.5- 09 6.7 and can't find one of the above three but they also are getting hard to find.

[@cass8144]

@@monsterram6617 so would the Eli live be a good option

[@monsterram6617]

@@cass8144 Yes, but just to be clear. EfiLive is a tuning platform. A person still needs to write the tune. If that person doesn't know what their doing you can still have issues.

I gotta be honest for the 6.7 Cummins and I love all the new parts. And one of the most thing I love about 6.7 Cummins is 2nd gen swap. I wish I could get a 4th or 5th gen Cummins with 68RFE for the driver license.

That pretty much covered all of the basic stuff i have on my 13 crew g56. I was looking for more info on internals you kind of had my attention when you said about the new Springs and stuff in the head but i already have the s&b box 5 in tuner and all that other stuff

[@clarkjohn2352]

And superstick trans with dual disc southbend clutch have a triple disc valair but i hated it.

[@garyosborn3168]

I think gearing is the most under rated upgrade that can be done. The right gears can just about make a truck pop wheelies with 150hp (even if it tops out at 42mph), also with enough gears and gearing, that same 150hp can go 200mph but it may take 20 min to get there ALSO I see soany guys chasing "stock performance" out of gearing. It's actually possible to re gear for better than stock performance if you know what's going on

[@joshuaquilliam2887]

This was like a long infomercial of the big money little hp gain mods. Cold air intake is pointless unless stock is actually restricting you. Yah stock turbo isn't taxing a stock intake. Want cold air? Try buying a bigger turbo and don't waste 500 (half a turbo) on an intake you will need to replace later anyway because it won't fit a bigger turbo. Fass or equivalent on a newer 6.7 is again stupid, the stock pump will take you above 700, I have done it on two trucks now 04 and 05. Air horn lmao is not the restriction on a Cummins, the turbine is along with the valve. Basically if you want to go fast, don't buy anything this guy said unless it's a tuner. Get rid of the parts that destroy your motor, then upgrade your turbo!. If you are an auto truck take out a second mortgage and get a revmax 850, if manual get a Valair street triple. Now you are ready for the big boy mods, Arp 625, Hammy 103 springs, and push rods. Now get yourself a 12mm or dual cp3's and some 150% minimum injectors (because you will go bigger, and buying injectors over and over gets old, I have bought 3 sets now). With a 472 or 476 you will be making some real power, not still playing with box tuners and intake horns.

I may agree that hitting 50+ psi on a stock head bolt truck is a bad idea but either way most people who have HG issues are from too much timing from a box tuner. I ran a custom tune from Higher Power Performance for a few years on a bone stock engine with no issues. Plenty of others have too.
