• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

99 GT

New member
Hey, new to the forum...i have a 99 grand prix gt and just ordered a Reprogrammed PCM from 3800 performance...anyone know anything about these??
 


I do not, but find a local member with a tuner. That is the best way to tune. By no means can one vendor's tune fit everyone's car.

I started with a ZZP PCM, then got a tuner... so I tune my own now. :)
