You will probably have +10 rwhp with a good tune on the VAFC. However, this would need to be done on a dyno with a wideband O2 sensor.

 

repost repost repost...hehe all the same mods too.
"hey i have exhaust (invidia), intake (aem) and VAFC...what am I making?" lol What I would do is go down to ur local tuner, and make a couple runs on the dyno, ~100bucks around here and itll really let ya kno =D good luck!

 

Actually, it wouldn't "really let ya kno". Every dyno is different, so he could go to 2 different places, and get 180 rwhp at one, and 230 rwhp at another. What would that tell him? Nothing! Dyno numbers are only really usefull for comparisons to other vehicles on the same day, before and after for mods (on the same dyno and preferrably on the same day), etc.
