PE mode just has a 60 second timer on these and once disabled they will enter PE mode just like any other. I am no expert but have tuned half a dozen of these HD trucks and that's all it took... The stock LQ4 tune from a Denali engine wise is basically identical just with no PE delay. Do a CASE relearn.. It's amazing what that fixed on mine.. Seriously. I had misfires that were not enough to show a cel but enough to keep my converter unlocked and it was down on power. Case relearn fixed all of that. I have a 3000 circle d I have been intending for my 05... Curious how yours turns out.

No lol. I used HP to do mine and my tune that let's me over rev the hell out of this old pig is still intact lol. I honestly had issues with the converter locking for over 2 years now... And all it took was a damn case relearn lol. Its like a 30 second process to do with HP lol.
