I don't want to start the whole debate on tuning and mod's and taking back to the dealer. Just want to tell my experience when I talked to the service manager today about just that. He said no way would any of that type of work would be warrantied. Like gnxs says you are probably just paying for a new motor in advance. He did say they would fudge things to the best for me should I choose to, but mentioned anytime serious repair would need to be done GM automatically makes dealer send picture of car's computer. Said something about some Microsoft operating system they use? Thank goodness we have w4m who seems to be one of the most smartest guys I have ever seen dealing with cars. This guy should be working for NASA.
