Hey guys. New to the forum here. I just brought a new 2020 L5p and looking to get it tuned and deleted. I know all the parts off the 2019 l5p work on the 2020’s. But my question is how hard is this to do? Can I do this myself or would I be better off taking it to a shop. I have mechanical knowledge but never took on anything such as deleteting a truck. Any tips or suggestions would be appreciated. Thanks!

Deleting is a thing of the past. Stock up on def fluid and a cushy saving for failed emissions parts.

Enjoy!

It’s first time posters like you that ask out of gate “hey I want to delete everything, what do i do” that folks consider suspicious these days. I suppose you could read a bit. And in reading, you will find out that dumbass kids “rolling coal” all over the mall parking lot videos have enlightened the shit out of epa tree huggers. Never mind the majority of folks that did delete did so because they were tired of paying a fortune to dealer wrench monkeys to fix bullshit emissions components that use rare metals dig up front deep inside the earth. Or that have been stranded hundreds of miles from home because a 50$ sensor went bad.

Save the world they say, black smoke must the root of evil they say.. Look it up, it’s in the same chapter as “look at me and my EV, we are saving the earth because i don’t use fuel”. As they charge batteries made with lithium batteries mined from South American communities thus poisoning water and destroying forests. All with power generated from fossil fuels.

Ah that rant felt better. Ima head out and get a snickers bar.

Well what the hell why not..... Go to youtube and use the search tool and find a video of people deleting their L5P to see if its something your comfortable tackling. I know they exist because I've seen them. Also, do some more searching on the ol google search engine it can don wonders. Lastly, I don't know how involved you are in social media but you can find just about anything you want on it if you're looking in the right places. Basically I say all that to say this, if you really want to "delete" your truck you will find the info you need without relying on others to tell you the information when it is a very sensitive subject right now and most people aren't going to open discuss it or communicate through a traceable device.

Finding the parts you want to set your truck up for "off-road" use only are getting harder and harder to find as shops and professional tuners have stopped offering said parts because the EPA is slapping the crap out of them with hefty fines. A shop in TX just got a 30k fine for doing deletes.

My question to you is why delete it? Why not leave the emissions intact and build upon that platform? PPEI and others are offering emission compliant tuning that adds the additional hp you want, makes the truck more responsive, increases fuel economy, reduces regens and def usage. What more could you ask for? Plus with PPEI's tuning, they have been tested by the EPA and in some cases are better than the OE factory tunes. PPEI recently installed a high end dyno and test equipment to further improve their tuning products and get them CARB certified.

I know that everyone thinks the DEF, DPF are the enemy and they have to be removed, gutted and left to die on the side of the road but like catalytic converters in the mid 70s to 81 we have to accept these emission devices and work with them and make them better not remove them and move on.

For what it's worth, I have a 20 Denalli that I am going to start beta testing today on street performance calibrations from PPEI. If all is good and I expect it will be, they will be available soon. Watch for new posts from myself or our staff at Synthetic Motorsports for updates on the 2020 tuning.

Well Good Luck because you have a long hard road ahead especially on the 2020. Because the programming is the "Magic Bullet" you have to have and those have all been fired and no more being loaded lol. I will be considering a "legal" tune when as mentioned above the test bed for the software is developed, qualified and in production. :) :grin2:


The old days are over never to be seen again. :(

Question:

To use PPEI street legal tunes in your L5P, do you have to buy and install a "cracked" ECM first? I don't know much at all about the whole subject of deleting and tuning since I've been driving the same LB7 since 2002 but planning to upgrade to a '21 or maybe a '22 and after all the horror stories I've read on the pre-'17 emissions systems, I am a bit curious on the subject. So far, it seems that the emissions on the L5P are a heck of a lot more dependable than their predecessors but still...

All ears!! I’m running the Banks stuff now, but I hear better numbers from PPEI.

Yes you still have to get a hp tunes ecm for $1800 and you void your warnteee. That way makes no sense to me why you would void your warrantee and still have all that junk in tact?

So a little devils advocate here...

Since all the emissions equipment is in place, seemingly the only item that needs to be changed is the ECU and maybe TCM. Obviously this voids the warranty of the vehicle if one still exists. Soooooo, it begs the question, can the ECU and TCM "hypothetically" just be swapped when warranty work is needed? Or is there some way for GM to be able to detect this? I know this isnt the honest way to go, but lets be honest, its crossed everyones mind.

Right now the only way to be able to tune a L5P is to first swap the ECU for one that has been unlocked. There is no way around it currently. I agree the new generation DEF and DPFs appear to be more dependable in most instances. According to my local GM service advisor, they have not had that much DPF or DEF issues at their location.

I don’t think they outright sell the hacked ecm. It has to be an exchange. But it guess the f you could get a ecm from GM, and send that in it might might work.

In theory maybe, but I am thinking they are going to look at the ECU code history and if there isn't a history for them to look at, they will become suspicious.

Understood. But, does every truck throw codes that dont always show up as CEL's??? In which case, besides driveabilty issues e.g. limp mode, how would you know if a code was thrown? The other angle i see is that even if dealerships are suspicious of something, they would need some sort of proof or reason to reject a claim and i dont think that simply being suspicious would be enough - am i way off base here?
