Could you confirm whether or not a car has the latest calibration update. I know G8s got a revised tcm and ecm update. And this 09 g8 is completely different than most I have seen. I believe this is an 09.5 tune because it seems to match closer to the gxp file. If you can tell me if the car has the lastest calibration updates. I’ll send you the OS numbers. Would just like to start off with the correct updated file.

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
