I think when mods become available for any sports car, the mod designers think that it will be installed most likely on a car with manual transmission. I've done a lot of research and talked with several dealers and I've come to the conclusion that the GTO's a4 transmission is a few tenths of a sec faster than the m6 in 0-60mph (a few tenths is a lot IMO). Maybe the manual is faster if you want to abuse the transmission, but I don't want to do that. My question is: If a computer decides when to change gears with an automatic, how will it react to engine mods like a supercharger? Will the computer think it's cool simply changing to the next gear sooner? Or will the computer have a fit because its programmer never taught it to handle a car with such different stats? Thanks.
