The cheapiest and easiest way to get more power out of your SRT-4 would be getting the Stage 1 upgrade ($325+), it will do more than any other single mod for a cheap price. Other than that I would have to say a CAI, you can get the K & N Typhoon CAI for only $200 + tax shipped, and the Mopar Performance cat-back exhaust, which is around $355 + tax shipped.

The best mods to do first are the oil catch can ($20+) and the MSD plug wires ($40+), the OCC will keep unwanted oil out of the intake and intercooler and the MSD wires will handle the high heat from the turbo as well as providing several hundreds times greater spark to the plugs. The motor mount inserts ($24+) and Mopar Performance short throw shifter w/booger bushings ($120+) are the next best cheap mods. Then there are the strut tower braces, front ($40+) and rear ($84+). And if your like most of us and love the great blow off valve sound, you can get a blow off valve ($65+). There are far more thin you can do to your SRT-4 as well, but most cost far more than these items.

Have fun and enjoy your SRT-4!

 

Do you have a link for wherever you bought this contoller. I have look at them b4 and found them quite expensive. They also have alot of different kinds, like 2 stage controllers and i cant remember all of the other ones i read about.

 

If you do get a boost controller don't set it too high....the stock turbo can only take so much. Beyond 19psi your not gaining anything. Youll also find yourself wtih a CEL Code for too much boost at partial throttle if your boost is set that high.
