Project 2007 Pontiac Grand Prix

[ViPER1313]

forgot this was SC'd. any plans for a pulley/tune? :twisted: i think i know the answer seeing as how it's you DD but i had to ask.

i have fond memories of my high school friends' grand prix GTP. took alot of abuse.

I would put a pulley on it but I would need to get a larger trans cooler for it, and it's plenty quick for a DD anyways. For some reason GM changed the ECU on the 2007/2008 compared to the 04->06, and the tuners only work for the earlier units (which have some issues in the later cars..)
