Car is running great but I have to have the dyno run to see if any of RENNtech's flash has been removed.
No way the RennTech is still there, not possible. I'm facing the same sutuation. Truck has been recalled, gotta go in next week. I've called Mega-Speed they will have to recalibrate the file based on the updated software. Said there would be no charge for it. Sucks that it'll cost me some 600ml. drive.
