Hey everyone, I've got a '02 1.8TQ and it's having a boost problem, I've had a search around but can't find much. By the feel/sound of it it's getting to a certain pressure then dumping, so if I floor it from under 2k to redline it'll boost up and dump several times, you can feel and hear it losing power each time it does this although it's less noticeable at high revs. I've changed the MAF, replaced all leaking pipes and fitted a Forge 007P, last thing to change is the n75 right? Any help is much appreciated. Cheers, Luke.
