JWT ECU Question

Hey people,
I need to know how much gain I'll get with the JWT ECU upgrade for the SR20. It's pretty much stock - just a K&N POP charger, and I plan to drop on a Greddy EVO Cat-back system soon (2-1/4").
Basically, I want to know what is the bang for buck???

With just an intake upgrade right now it isn't a good idea to get an ECU right now. You won't feel any significant power gains. If you want a good bang for the buck, get some JWT cams which about the same if not less than an ECU upgrade, or a set of hot shot headers if you aren't planning to turbo your car.
