i have both the greddy type s and rs. both have a similar problem. when the car first starts the piston sucks up just a little. when gas is given the piston pushes outward into the piping......not right. on my buddys srt-4 it sucks in. am i using the wrong vac line? its t'd to the fuel pressure line just off the throttle body.

the piston should push into the piping when gas is applied, thats what seals the boost in

but it doesnt open all the way. under full boost when i let go of the gas, the valve does not open.

the vacuum line should see vacuum and boost... when you are idling, disconnect it and feel the hose, if its sucking then that part is good... if you tee the line goign to the boost gauge and your boost gauge sees vacuum and boost then you should be using the right one... otherwise, you have two broken bov's
