the wastegate vacuum hose has a manual valve t'd into it, so i removed it today and it now hits around 12psi again but the engine doesn't cut out. it still acts a little strange sometimes when its on 12psi i.e hesitation etc. but overall seems to be running better. and no fun police now lol. looks like its making 12psi at around 3000-3500. couldn't really watch but it build really quickly.
