Ok this one is for the really clued on, I've got a 89 r32 gtst 4door, engine mods are FMIC, full exhaust, Apexi power filter insert(yep running stock air box), & alloy rad. Now prob is, when car hits full boost, 9psi(lol), the rear window jet sprays the back window! So I was thinking maybe a vacuum hose somewhere is plumbed wrong. Not real sure any help would be appreciated. I know it's not a big prob, but is really annoying, & don't want to just disconnect it.
