Trying to make sure I got everything I sorted out before I start tuning my Supercharged 98 Vette. I Swapped the PCM from a 2001 corvette. My HPtuners has 2001 corvette model license, so I should be able to use that PCM without any more credits and convert to 3bar RTT (I was able to convert a 2001 file I downloaded from repository from OS 12202088 to 3bar RTT). I've read some things that a 2002 operating system has different values? Would it be worth it to buy 2 credits to use a 2002 operating system?

Anything else I need to know?
