Hi Jen, ...Sorry about your computer troubles. I think many mechanics are "remove and replace" people who may not understand anything different. I asked a guy at my dealership about the ECU Tune and whether it may effect my warranty. He told me it would not.

I think the best bet is not to tell them the tune has been done unless you get a crackerjack mechanic that comes right out and asks you because he notices different computer settings have been changed.

I think the reason many dealers tell you that any modifications to factory settings may void your warranty is because they figure you did the mods to race the car. They don't want to be responsible for repairing abused cars on the manufacturers tab. But, that's just my humble opinion.
