2) If I get a professional tune, will the new configuration get wiped out when the battery is diconnected or do the settings get saved into eprom chips or something, i.e., if I pay good $ for a tune, will it all get wiped out and I have to get the car re-tuned costing me even more $?
3) I think I already know the answer to this one but does getting a performance tune automatically void the warranty on the engine? I'm not worried about the warranty on the exhaust but the engine is a different story.

1 The ECM will not learn and calibrate itself, a tuner will need to do this for you.
2 The calibration is written to the ECM and when battery power is disconected the tune will still be there.
3 They may decide to not cover a claim if a different calibration is found. We have tools that can make the new calibration appear as the stock calibration to the GM tech 2.
