What kinda budget are you on, and how fast do you want it to be? My first suggestions would be 4.30 gears, off road pipe, a K&N, and maybe a tune.

Hey Kelly I bought my wife an 03 gt for mother's day but it is gutless. she is happy with it but where do I start with getting a little power without affecting driveability? I actually think something isnt right with it because its way too sluggish but it runs perfectly and only has 70k miles on it. Im a pushrod guy so this is all new to me.
