Got all the stuff put into my truck and flashed and then I have some codes saying no communication with the tcm and pcm so I called PPEI and they took control of my computer and said I?d have to get ahold of hptuners, so I did that. I?ve been dealing with them for a week tomorrow making no progress it doesn?t help it takes on average 2-6 hours to get a reply from them, for example I was asked to send some files to them so I did but I had to work so I didn?t send them till after they were closed so obviously I wasn?t expecting a response until today, which I still have yet to receive so then I asked for a confirmation to see if they received the email and that was sent 2.5 hours ago and still haven?t heard anything back. The truck will fail to flash any tune I try to write to it along with still having those permanent codes so the truck will start but the transmission isn?t working along with the throttle. So as of right now I am 100% regretting spending almost 6k for an ECM and TCM. So I would highly recommended not deleting your truck until they have had more time to fix any and all the issues they are having
