Hey guys. I have a 1999 Grand Prix GT with a L67 supercharged top end. I am about to beginning tuning it, and I've heard I should start with an L67 bin file. How do I do this? Won't HP Tuners detect a different OSID and VIN? Please help!

When I top swapped my '99 Regal I started with an L67 base cal from a '99 Regal GS.
To do so, you will have to license the new cal and perform a full write in order to flash it.
2006 Pontiac GTO, Torrid Red, M6, "LS2.5"

Your best bet is to license the entire '99 Grand Prix 3.8 spread (4 credits). You'll get unlimited tunes for unlimited PCMs for *just* the '99 GP 3800 for same price as two licenses.
