Thanks for the replies guys, it's a baileys dump valve that's on the car, was on when I bought it so no sure how old, anyways I've stripped it off and although everything looks ok, when pressing the piston it moves just a bit too easy, don't know if thats how it should be, i'll borrow my mates and see if that helps, before purchasing a new dump valve. Thanks again.

Hi guy I'm new here I have an 03 wrx which has has a few engine mods, I have an any forest print out of 340bhp, however my question is, when on full throttle it seems to be continually blowin off boost, it's not doing it when drivin normally, only when foot is flat on the floor, any info on what this could be would be muchos appreciated .
