Default What Other Mods??

What other performance mods do you guys recommend for my GXP. I already have: Magnaflow Exhaust, QTP Cutout, K&N Aircharger Intake, and I will soon get it tuned. I want to keep it $200 or below for each mod, and I want it to pass NY inspection. Any input is greatly appreciated!!

-Nick

The TBS has to be for a Chevy Trailblazer V-6, 04 I think. They make 2 for the TB, V-6's, one that is triangular and one that is squarish like ours.

There are many, many mods to do under 200.00 for each one. Most of mine were except the downpipe and transmission. After headers the only other N/A mod I can do is a ported intake. I am not going to cam it either since the 1.85 roller rockers do plenty up top. I only paid 200.00 for the SLP 1.85's I have. I bought them out of the classifieds on this board. If you can find them that is a great mod.

It does add plenum volume. I could feel a difference. I'll be selling mine soon.
