I was wondering my WRX is stock and when i pull uphill there is a dpi in the power curve i can feel a little after the turbo spools up like 5.5 rpm then goes back up like 6 rmp this is weird and i can actually feel the power go down.. i read import tuner DEC 01 issue and the dyno chart of the power curve seems to correspond with what i feel.. do you guys feel the dip too?? what do you think causes it? the intake resonator??anything else ?? for you guys that have modified WRXs what did you change that eliminated this dip??
