Mine dyno'd at around 235WHP (uncorrected) at 5,500ft above sea-level last year. Identical numbers to those pulled by STi's on the same dyno around the same time. Buddy of mine pulled about 5HP more on the same day IIRC, with a 'stage 4' WRX.Originally Posted by bigwrxguy
I was running stock boost but had the panel filter pulled. No other 'mods' at that time.
