I have a 99 GT.....Granatelli 75mm plenum, BBK 75mm TB, K&N filter in modified OE induction. Exhaust is OE manifolds, modified factory H-pipe into Mac Pro Chambers. Im planning on CAI, cams, long tubes, 3.73 gears, hundred horse shot, and a flash tuner in the near future...... im goin with AFM on the cams, BBK on the headers, FRPP for the gears and NOS for the nitrous, but im a little lost on the tuner and CAI....what would be some good suggestions going by my mods and planned mods? I keep hearing SCT for the tuner, but theirs are more geared for highly modded and/or forced induction engines. I don't have plans for forced induction, so would diablosport be the better choice? I have no clue on the CAI..... any suggestions would help.
