the vac is at twelve and no the screw is where the original screw is posed to go ya understern??????

 

if the vaccum is at 12... you have a leak somehweres. a 4G63 is suposed to run @ 18 in/hg... give or take 1. if youre only pulling 12 in/hg, you have a small leak somewheres.

and, the whole screw broke off and theres nothing there, not even the lock nut? i thikn wht you might have to do is send it back to GReddy and have them repair or replace it. its happend to a kid who tried to adjust the BOV w/ the nut, rather than the stud, and ended up stripping the threads. he said they replaced it for free. might wanna give them a call and see what they say. just tell them you were going to adjust it, and when you were undoing it, the stud twisted off w/ the lock nut.

 

ya but i didnt buy if from greddy i got it off my friend and it was tuned to his motor and then we went to go do it and shit flew....dunno

 

call GReddy tech support, and ask them if there is anything they can do to help

 

thanx
