Damn can't wait for install video. I have a 19 Duramax & got all the stuff sitting my garage for a year now but have no idea what to do first.

[@darkirondiesel]

Editing it as we speak!

[@GL5P]

Hell yeah ive got downpipe and kit waiting as well cant wait for this vid

[@bradycaroll2198]

You answered my prayers this is why I love your videos ❤

[@NorthernHDrider]

Awesome, thank you for showing the details and how the steering wheel works. 👍

[@georgezhou7961]

hell yeah finally a L5P video!! Just deleted mine about 2 months ago and loves it. Keep more vide come!! Love from Arizona

[@alondraz2836]

Who did you get the tune from?

[@Stiff3]

Gonna do mine once i get my parts in a bit here,this should help out quite a bit.thanks a lot

[@daltonbuck4502]

Awsome video, thank you so much man! Very helpful

[@guillermotaboada3235]

The video was perfect man, thanks a lot 👍

[@darkirondiesel]

Glad it helped!

[@joenowe5964]

this is awesome content! Making the L5P look and sound less intimidating lol

[@philipneville3172]

Awesome video man

[@nombr]

Good video man, I don’t have a l5p but always enjoy your diys. I really do like the cruise/tach for sotf. I used to run a switch for my 6.7 psd but got rid of it because i thought it was causing issues (also never took it out of 5 lol)

[@darkirondiesel]

Haha ya the temptation is real. I’m just running a single 75hp tune on my Cummins for that exact reason.

[@briang7870]

​@darkirondiesel I'm running a 75hp ccs tune as well and get really good mileage on my ho but vgt position doesn't close all the way during cold weather warm up.

[@DTSstrength]

Do happen to have an instructional video for the transmission tuning process? Thank you!

[@fireflyraven2760]

Um quick question say you are doing this to more rhen one vehicle.do you have to reinstall this update in oreder to continue the proccess or is it just it is now o .the computer so no need

[@zachary2417]

What’s your thoughts on the gmc ? Should do a compare video on your 5th gen and this l5p pros and cons etc

[@darkirondiesel]

I’ve always liked duramax engines. They are fast and I think they are reliable. But now a days they are all nice and reliable for the most part. So if I were truck shipping I’d just go drive them all and pick the one you like best. My next truck will either be a duramax or powerstroke just to switch things up a bit.

[@marcog3210]

Am I missing something or is the oil pressure at like 500?

[@slidewide1999]

Originally the L5P you had to do an ecm swap right, similar to ‘22 and later Cummins trucks? Do you think this unlocking procedure will be available for the Cummins?

[@darkirondiesel]

Great question, and to be completely honest, I don’t know. I’ve been hearing tuning companies saying their close to figuring it out, but I’ve been hearing that for over a year now. It took them quite a few years to figure it out for the L5P so hopefully one day they figure out the Cummins, but I wouldn’t hold your breath.

[@panic4949]

Was going to ask the same question. Really don’t want to pay $4000 for an ECM and Unlock.

[@aden6128]

It its 😏

[@1Bagged17]

I used to have a 2018 l5p and deleted it myself and I traded it for a newer 2021 l5p can I reuse my e41 unlock device on this one? Or do I need to contact a tuner?

[@JoseMedina-jt7ip]

What do you mean when you said Emissions on and off. Im doing a full delete on my 2017 DURAMAX. My service exhaust fluid light keeps blinking and the Engine light is on. Will the tune take care of all the emissions codes (the light that keeps blinking) or will I need to do a force regen or something to make the light go away before tuning?

[@darkirondiesel]

If you get the kit I used shrsl.com/4ajh9 then it should remove the emission light but it might take a couple tune revisions to get rid of it. That’s why you always tune first and confirm the tune was successful before removing any parts from the truck.

[@frederickcarrozza1408]

so you tuned first before the delete, when you deleted it did you need to upload a different tune for being no emissions? how is your truck not throwing codes for the emissions is it the can bus plugs?

[@darkirondiesel]

The tune that comes with it I did on the other video is an “emissions off” tune which turns off the emission system and blocks any codes from popping up.

[@509livin8]

I have a question. Why did you tune with HP Tuners? Dosent the kit from thedieseldudes comes with the tune plus all the parts you need?

[@darkirondiesel]

All this was from the diesel dudes.

[@carlosnava8166]

Hello friend, thank you for your videos. I wanted to ask if I need to delete the DEF system from a 2020 Dodge Ram turbo diesel PCM Cummins CM2450B. Can it be done with HP Tuners, or could you advise me on how to do it? Thank you very much.

[@darkirondiesel]

Hey you need this kit if you want to delete your truck shrsl.com/49eq1

[@kadynhughes8151]

Do you have to use the beta version or can you use the non beta version as well?

[@darkirondiesel]

Must use beta

[@grayhancock6953]

Are you making a egr delete vid?

[@darkirondiesel]

Yup editing it right now. Should be up in a couple days.

[@jacebond1717]

Does their kit Include TCM tuning as well?

[@darkirondiesel]

No I believe you need an unlocked TCM for that, but you could email them about that. Or contact GDP tuning after you purchase the kit and they can set you up (that’s who writes the tunes for the diesel dudes)

[@andresauve4878]

After tuning I was getting code P0700 and others that wouldn’t clear. Luckily disconnecting the battery reconnecting and checking no codes appeared.

[@hauto383]

I know they were having some major issues with the SOTF on the L5P. Have they got the kinks sorted out with that now and its not longer bricking ecms?

[@darkirondiesel]

I’ve never heard of guys bricking their ecms on an L5P so yes I’d say it’s sorted out.

[@lylenelson7446]

I'm running motor ops sotf running. I usually stay in tune 1 which is the 85horse tune and might occasionally use tune 2 or even 3 for a smile. Never use tune 4 or 5 because I don't have a built transmission. I've had zero issues just pure joy and peace of mind

[@boistoys5451]

When will they have something for the Baby Duramax ?????

[@318haze]

Did the mpvi3 come with the 20-23 kit or was that separate?

[@darkirondiesel]

Yes it comes with the kit. For legal reasons they can’t advertise the mpvi3 coming with a “delete” kit.

[@318haze]

@@darkirondiesel thanks

[@dylanbenner3446]

After upgrading the ECM and uploading the tunes, is it okay to still drive before doing the delete?

[@darkirondiesel]

For a little bit ya but they don’t recommend you drive more then 200 miles like that. It can damage your engine. And keep it on the lowest setting.

[@gageandrews7179]

Which model unlock box is this? Is it on HP tuners website?

[@darkirondiesel]

Not sure but it comes with this kit shrsl.com/4ajh9

[@darkirondiesel]

Not sure but it comes with this kit shrsl.com/4ajh9

[@erikeberstein6460]

Hey bro, do u got a website??

[@darkirondiesel]

No man just shoot me a message on instagram if you need something

[@woodysapper7]

Need a 3.0L delete..

[@TheIamdevin]

Dirty diesel has them on their website now

[@darkirondiesel]

I’ll try to get a video of one in the future

[@marvz71]

Edge has the cheapest unlock option out there now I believe with the bonus of the monitor after the fact. Can load the custom tunes in the device as well for under a grand.

[@darkirondiesel]

But you still have to purchase the tunes from a company don’t you?

[@MikeOxlong69695]

I can’t be the only guy wondering if you can just tune the egr and def systems from working? Why does the egr system have to be removed? Imagine the valve would just remain closed. leave everything in tact but remove entire dpf system. is there really no way of accomplishing this with a tuner even now? Hypothetically speaking

[@darkirondiesel]

The egr can be left on the truck, you just need to unplug it. The exhaust NEEDS to be changed though. If you wanted to keep a stock look you could drop the factory exhaust, take it apart and punch out all the internal filters then bolt it back up under the truck. The main thing is getting the restriction out of there.

[@MikeOxlong69695]

@@darkirondiesel any negatives if you were to leave the egr and just unplug it?
