Hey guys i have a 04 GMC and just installed a cam but the pcm is locked...I had an 06 Silverado PCM layin around and swapped the pcm...it runs and i started tuning it the only problem i see is that tha throttle only opens around 58% @ WOT...is there a fix to this or has anyone else had this problem....when i put the locked pcm back it works fine 100% WOT...Thanks
anyone!!!
probably different ETC parameters for the different years causing the problem..
I think it's more along the lines of the TAC module and APP sensors (pedal). They are definitely different between the 04 and 06 trucks.
