I have the SAME problem! I have heard from Will (at overkill) and other 06+ owners the only problem they have had is the fuel reads backwards. I also talked to ZZP and they said nothing about ANY problems...Will sent me a reply back and told me the problems that he came across. I take this as 1. ZZP didn't wanna tell me the problems,2. ZZP didn't know about the problems, or 3. ZZP never done a 05 PCM on a 06+. So...Thats what I got so far! But please keep me posted on what you find out!!!
