Hi guys,
although I've read a couple of times through the FAQ, I don't fully understand it: http://www.hptuners.com/forum/showth...ir-Differences
Here's my situation: I have a Pro interface with 8 GM credits. So far I only used 2 for my 2002 CETA. Now I want to try a very custom flex fuel OS on the same PCM (and same VIN) that I already licensed. HP Tuners tells me that I need to use 2 credits, again. If I want to try another custom OS, would I need to use 2 more credits, accounting to a total of 6?
And if so, wouldn't it be wiser to use 5 credits to license the whole 2002 FBody year for unlimited VINs? And if I do that, does it include any custom OSes for the 2002 FBodys also?
Thanks in advance for any hint
