ran perfect, then it sat on a shelf for a year.....

re-installed and went for a cruise, with the boost backed off all the way i was overboosting easily to 8,9,10psi.

took it off and just went to the gate and i was getting 5psi.

when i suck on the exit nipple i can easily suck in air

when i blow in the inlet nipple i cannot push in any air to the device

took off the nipples, inspected the ball and spring, no damage, no gunk, clean as can be.


any ideas?

just found out that when i back it off too far while sucking on the exit it starts to block the air.

so maybe i had it backed off too far.

but the odd thing is that when i turn the **** to increase boost i can suck on the exit just as easily as can be.
