I would go for a short ram intake and a Diablo chip.
The short ram will wake it up a bit and the chip should pep up the auto trans. That would be a good start and not too expensive.

 

Welcome to FF! Well honestly if you want some kick your going to have to pay some money. You can get a good tune from Tom (1Turobofocus) its around 400 shipped a believe. As for intakes noone really give any benefits. Our stoks sytems work well with a K&N filter. You could always look into a SVT header swap and a 2.5 flex and exhaust. but thats a lot of $$$

 

i got a jba shorty header and focus central ORP off ebay for like 150 to 160 for both and they worked really good together to give it some power

 

This won't really add any power, but removing the resonator from your airbox will make the car SOUND much better -- it will feel sportier to your "butt dyno" without being obnoxious (the resonator is the black box hanging off the airbox on the side nearest the driver's side fender). Cost: FREE.

Good how-to posted here:

You might want to try the Iceman intake mod as well -- very cheap, and it turns the resonator removal mod into a minor performance enhancement. Cost: About $5.

I got an intake for it it looks like an ebay one the filter stick down by the front bumper. It seems to help a bit and sounds good. I am no stranger to tuning I havent had anything really of note but I am more looking for some cheap "tricks" Alotta things I can do myself. God the tranny feels so weak on this car.

 

you can port the tb and intake..helps throttle response...search threads on here
