I know u guys r wondering what a subaru guy is doing on ur forum. A buddie of mine and i have looked at 2 srt-4's. Both have the bov blue plate and aftermarket intake. He's driven both cars and neither will boost above 10psi at wot in 3rd to redline or 4th up to 4000rpm (kinda run out of room). I've read some of the other posts about weather/temp. We live in central ohio. My WRX has an electronic bc, so temp isn't an issue. At first i thought of a boost leak on the first car, but the 2nd did the same thing. My buddie is a little gun shy until he gets some good answers. Any other ideas?

 

it's probably just the weather. i've seen these cars go as low as 4psi on really cold days.
