both these are in my price range. just wondering which one would be good for a 05 wrx w/ basic boltons. i have aem intake, borla hush catback, greddy bov, and 2 gauges: ext temp, and boost. pretty good start with 40 miles on my car lol. and for tuning im lookin at these too. i just know that the safr by hks has a cpu in it so it can do all the major tuning by itself, but in your opinions which ones better?
thanks
andrew

 

For your mod level, you might consider a Cobb or EcuTek reflash of your ECU. The power gain and driveability will be better than those universal add-ons from HKS and APEXI.

If you want to tune yourself, the UTEC is popular.
