heya dudes...just wondering if it is worth it getting an Apexi S-AFC II for my car.

currently running a D16a8 with Js racing air intake, headers and mufffler and soon a 2" cat back pressbend.

Now i know u can get cams, valve and valve springs, but thats alot of $$$.
If i purchase a S-AFC II, will this increase power by tuning it right from the mods i have currently done?

what do u suggest ?
