I have an 02 wrx wagon ap flashed stage 2 with a megan header full catless turbo rfl exhaust stp intake
and perrin turbo inlet tube sti IC w/ a crushed BPV and thats it as far as the engine although I did just replace the three engine mounts since mine were pretty much beat.
the problem is today on my way back home I got on the car to pass a mustang when the boost practically tossed me like a cookie into the back of the seat.
when I checked the ap since it maintains your highest boost it said 22psi in 4th gear so I started playing with it alittle turns out the boost is much higher than it should be what happens is it picks up sometimes quicker than others and hits high then just drops off then picks back up again and then drops again then picks up and drops again you get the point by now right it does this in all gears sometimes it wont pick up for quite awhile then it just spikes way up.
my highsest boost is usually 16.8psi in 5th.
I have a few friends who seem to think its the crushed bpv so I'm gonna replace it with the original one and check all the boost lines for leaks. I also just reflashed the ecu to stage 2 again (which took like 2 seconds so im guessing thats not it.)
I myself have done some research and the only thing I can find is maybe if its not the crushed BPV the boost solenoid?
as far as the car it still idles fine no stranger sounds then it usually makes any help would be much appreciated as im moving to Texas from Pennsylvania on sunday and the car needs to be ready for the trip.
