Specifically post #25 through #28.
So if reading correctly, its best to jam a 04 OS on the ecu that matches what i drive and then tune or make changes from there. Guess i am lucky i got an 04 ecu from the junkyard for my test ecu. Will plug up to my truck to see if removing the vats and minor tweaks worked. Thanks for the help, came across that thread before but guess i didnt really really read it.
