I bought a 98 gtp with 3800 sc v6 recently and have some question. I want the car have more power than the stock and Ive read alot about what it takes. I have a local guy that is great at tuning but I need to know these things. I am going to buying some speed daddy headers will that cut out the stock u bend? Is there any CAI kits that are worth it or should I just use one of the dyi guides? Also think about getting some.different ratio rockers but really dont know what to get. So givin all this ill have headers, no u bend, rockers, 180 stat lower temp plugs, no cats and probably straight pipe tbh, and if someone can point me to some decent rockers chalk them up. What size pulley should I put on my sc? Of course then I will have my guy tune it. With all this done will the car still be very dependable? I will want to drive it to work and maybe on a decent mileage trips. What kind of mpg would yall think I would get under normal driving? Thanks for reading this and I hope to hear for everyone on their thoughts thanks again.
