03 wrx 284hp/269tq
03 2.0+vf22 127,xxx
Event: dyno pull
Location: Drift Office
Ambient Temp: 71 f
Elevation: sea level
Car: 2003 wrx 127xxx
Tuner: Bill + Bob Drift Office
Dyno Info: Dyno Jet
Transmission: 5spd factory
Peak HP at RPM: 284 whp @ 6000 rpm (SAE)
Peak Torque at RPM: 269 tq @ 4000 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
Target AFR: 11.5
bosal divorced shorty dp
gutted stock mid pipe
3'' boral catback
titek up pipe
modded stock injectors 820cc scaled to 65% DC IIRC
Driveline Modifications: stock clutch and trans
Suspension Modifications: perrin sways/ kartboy endlinks
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!

lol, it says peak boost is 28.6psi peak. I assume you meant 18.6.
