Probably a stupid question but I'll ask anyways. I have a 2015 Camaro SS. I've been considering getting hp tu ers instead of EFI live to tune my car. Im curious about the 8 credits it comes with when you buy it. Do I need a couple of credits to unlock my vin essentially and then I can tune that car as many times as I want ? Then use any remaining encase lets say I trade my car in for a new car ?
