Redline03GT

My 03 GT 5 spd has 8000 miles and the following modifications:

BBK Air Induction w/ K&N Filter
BBK 70mm Throttle Body
Trick Flow Upper Plenum
MRT High Flow H Pipe (2 Cats)
Flowmaster 2 Chambers

I am NOT planning on removing any of these parts because i am happy with my setup. Besides modification in the price range of a blower, what should my next performance mod be? A little giggle juice perhaps? Some headers? Keep in mind i wanna stay legal.

I say rear gear or pulleys

GEARS, pullys, headers, some cams maybe, then get her dyno tuned.

If i get a programmer, should i go with Diablosport or Hypertech and why?

Don't get a programer.... Find a dyno around you and have them do a custom chip to your car after a few pulls on the dyno... No mail order stuff...
