U-bend delete, hi-flow CAT convertor, re-programmed PCM, 3.4 SC pulley, CAI/FWI to name a few. All depends on how much money you want to spend.

Also, when changing supercharger pulley size you'll need to adjust the heat range of the spark plugs accordingly to prevent knock retard (KR). On a 3.4 pulley drop one heat range colder.

Thank you for the tip,I was planning on getting the smaller pulley and the thing you need so it wont knock,and also a new thing for my computer haha Sorry i cant remember the name's of things,i think it was that PCM thing you mentioned...anyway the rest of it should i do after the pulley and pcm? How much do all the things for the pulley and pcm cost? A friend said about 450,does that sound about right? I desperatly want it faster but im trying not to spend TOO much,haha. But thank you for the tip!

We all feel the need for speed.

Here are some ballpark figures not counting labor and special tools:

Press On 3.4 SC pulley - $60.00
ZZP v1.0 PCM - $70.00 or DHP v1.0 - $99.00
(6) Autolite Copper Core Spark Plugs 605 - $18.00

Name Brand CAI (Cold Air Intake) - $200
U-bend delete - $60.00
Magnaflow Hi-Flow CAT - $55.00

The best mod for the GP if you are keeping a Supercharger, is an IC. If you want to keep your stock trans I wouldnt plan on going faster than low 13s.
A full IC an Rockers can be a very strong combo that most people can install themselves.

Good luck modding!
