[QUOTE="svtfocus2cobra, post: 16687453, member: 21786"] I can tell you where you might run into some pitfalls eventually. Just had a 2019 Duramax in for no start due to loss of communication on the CAN BUS. The customer had just done all the deletes and had a programmed TCM and PCM installed and it worked for him for a couple days before the truck started acting up and eventually stopped running. Our tech was able to re-establish communication and figured out the issue was the glow-plug module or the harness that was bad, and when it would lose communication you can just wiggle it some and regain communication. For him to fix that we will have to replace the module and he will likely have to install all of the original modules to be programmed together because GM's new programming update supposedly programs the entire vehicle if you are trying to program one module. The customer ended up taking the truck to see how bad it was going to act up on him before he makes up his mind on how to proceed. The work we did on the truck cost him $1200 in testing and repairs and he will likely have to spend another $700 or so to fix the issue. It's just become a huge pain in the ass to work with the deletes because of what they are doing to, what I assume, make it harder to tune and do deletes on diesels. That's obviously GM but I wouldn't be surprised if Ram and Ford are going down the same path if they haven't already. [/QUOTE]
