On a Tial 38mm. Anyone have this? Only has like 500 miles on it. Vac lines are hooked up correctly, boost controller is fine.

 

Heard of this? Is what I should have asked. It's late.

 

How do you know its stuck?

 

yep, we had a stuck one. jammed itself shut and wouldnt open until i gave it about 35psi of compressed air. oh and it made the car boost to 2 bar, as in 29psi. i think they are crap, and i dont like how they are designed with such a thin surface for the gasket. which also blew out.

 

overboosting.

 

K thanks. Too bad cus it was pretty much brand new.
