Peak HP at RPM: 284 whp @ 6000 rpm (SAE)

Baseline hp/tq for a stock on same dyno: I have no honest clue, but my stage 2 wrx did 219hp/219tq in 2009 on this dyno
Target Boost: 18.6 psi peak

Like stated above I had my stage 2 wrx dyno'd on this dyno in 2009 with 219/214 and returned after a turbo install to compare to my baseline. I was able to gain 65 hp and 55 tq from a used vf22 I bought recently from a member here.

the graph posted below shows my old stage 2 tune from 09 (yes it was lean, that was corrected after), vs my new tune. Boost holds smoother with the vf22 vs td04. The torque curve is also much better.



here is a video of one pull. sound quality is poor!
