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.

I found this to be all engine calibration segments for 7603 OS.
There are not confirmed but size and identifiers matches, so use on your own risk.
There is also some 5.7l segments.
Thanks! Looks like useful information for research!Originally Posted by kur4o

Awesome! Just curious where you found these?? And do you have the segments for engine Diag as well?
