    L36-L67 Top Swap

    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.

    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.
