Hey clearly not the bov as 3 different types don't work.. its my setup/vaccum source i am told... Ive tried to put it in the throttlebody ports with no luck teeing all the 3 port vaccum plug to give a better vaccum to bov but still no luck.. A mate of mine has a gt starlet and hes bov is straight after the turbo we tested my bov on hes and it blows off on idle and at 0- 2 postive pressure ..Something is really weird, I continue to drive the car with 6-7psi without bleeding the boost.. could this harm my turbo short term ?
