So, I've finally gotten back on my feet and gotten a good job and am looking to play with my Grand Prix GT a little. I've been surfing around ZZP's site and 3800 performance. A few things caught my eye, but I'm a little confused. I really like the idea of the ZZP PCM 1.0, but I'm having the hard shifting issue with my transmission, would this destroy it further? Which is better a set of headers or the ported manifolds ZZP offers? From what I gathered, the headers cause a loss in low end torque? So aside from those questions, where should I begin modifying my GP GT. Keep in mind I'm a college student and this is my daily. I'm okay with just bolt-ons, headers, downpipes, CAI etc. But where to start?
Thanks,
Brammer
