7603 OS
Looking for an 04 7603 OS for 6.0L and manual transmission please. I have one for the 4L65E from a Yukon Denali. Not sure what parameters to change in TunerProRT so would like to compare. I did compare the OS I have against same OS for 04 Corvette M6 and matched all the transmission scalar, flag, dtc settings. Not sure if that's good enough.
