I have a CAI, e-fan and exhaust done so far im looking for something else to add a little more power cheap and easy weight is not a issue since i have about 300lbs of stereo in the rear.
other things to help would be also a goo plan.

 

I've read that the IPD adjustable cam gears can make a noticeable improvement in power, especially in the lower RPM range. The gear is kind of pricey but I do see them every now and then on ebay. Other then that it sounds like you've reached the peak, at least when it comes to affordability.

 

ive been looking into different coils would this make a difference too and if so what im i looking at getting?
