Have a 2004 comp g that I replaced the transmission with just a standard hd from a 2007 with a supercharger but no tap shift.
Believe I need to program the pcm to a regular 2004 supercharger tune so I’d have the correct 2.93 gears and no manual mode for the tap shift.
Can the dealer do that?
Or do I need a tuner that has hptuner to so that? Would they have all the stock programs that they can just download them?
I know these cars are almost 20years old and there tons of info here just not much action. If anybody has any in-site that would be awesome.
