I am new to the new era of hotrodding and have a big learning curve to work through, so please excuse me if I seem a bit dense...

I recently bought my 04 GTO and am unsure if the previous owner has done anything to the tune on the vehicle. Is there anyway of telling besides having a dealer reflash it. I read the manual and I just want to be sure I'm not going to install over a non-stock tune. If there isn't a way I will have to bite my lip and deal with the dealer. Thanks

Well to be 100% sure yes deal with the dealer and they will reflash it back to stock if there is a flash in the car. If you do not have direct contact with the previous owner then you do not really know. If you contact us we can look up somethings and see if you have the latest calibration or not. 800.531.5484
