Hey guys. I have only made a few mods to my 1998 GT convertible including FM catbacks and K&N FIPK. Realistically speaking, how much rph should I have? I have never had the car on a dyno, and am wondering what the real amount should be. Also, I am considering an Accufab plenum and throttle body. Should I go with 75 or 70 mm for this sohc? Is it worth doing? I am also serious about buying a Superchips microtuner, and am wondering if I do all of this, will I feel a difference? I have recently done the 3.73's and will stay na for a while. What do you think?
