Well I decided to try the Turbo Xs BOV since all the car could pull with the stock BOV was 13 psi where it normally would be 14.5. I hadn't adjusted the boost controller.

Anybody have any hints for setting up a Turbo XS BOV?

How do you know how many washers do you add? The spring I have is cut, so I'm not really sure if I doing this right. I have no instructions or any other parts of the kit.

With the cut spring, the valve flew open under a boost test. So I added about 4 washers. It still leaked a little air so I added about 4 more. Still had a slight leak but I didn't want to put too much pressure on it.

Took it out for a ride and now it boosts to 15 psi and climbs to 16. Much better.

At low decceleration, snapping the throttle closed sounds kind of wierd, hard to explain. At full throttle runs, getting off the throttle give a sharp tone woosh. Does that mean I have too much spring pressure?

FYI, I removed the bell horn from the BOV to quite it down, it's way too ricey with the horn on it.

I'm not sure if that is what I was experiencing or not. I know I had trouble with the BOV not wanting to open all the way when it was on my 14b car, hence the reason I cut the spring. Once I cut the spring I couldn't hear it leak at all and it didn't seem to feel like it was leaking though I never did a boost leak test to determine this. Once the spring was cut it opened exactly as it should though. Also know that the screw on cap where the spring goes in is also an adjustment point. I had mine on the last 3 threads with the spring cut and that's where I felt comfortable with it.

I believe the main reason I cut it was because it wasn't responding under light throttle.

How much boost were you running?

With the amount of washers I have, it does sound "labored" when opening. Almost sound like I can here the plunger snapping shut under light throttle.

I was running 18lbs at the time and it would open and shut pretty efficiently after I cut the spring and adjusted it out most of the way.
