I removed my PC back in December due to the cold seemingly causing glitches in my system and the truck kept going into limp mode. After removing it, I did some research, and found out that it was probably caused either by me messing with it while driving, or by the cold causing the connectors to separate ever-so-slightly as to cause voltage changes as the heat blew on them and they warmed up. In anycase, I decided to leave it out for the time being, but I did find the OP here, and made the mod using Alpha... Yesterday, I decided what the heck - it's warming up - so I reconnected my PC into the system - and if you think the PC was good by itself - damnnnnn - YOU NEED to make the mod AND use the PC at the same time! In Sport mode, it's like driving in Sport+... I haven't even tried Sport+ at this point... Actually a little scared to.
If you do this - please post the results - 'cause I'd like to know if I'm just crazy or if it really is like a demon being unleashed!
