Default Adjusting a 50mm TIAL BOV - Got a Question?

I just set up my 50mm TIAL BOV and its leaking a tinny Bit at idol (I think?).

Hard to tell without having someone work the pedal for me BUT I think its leaking a Tinny Bit at Idol. I just wanted to Verify. To snug up the spring DO I tighten that small allen head screw that’s in the middle of the valve Under the Vac Port. If so HOW much should I turn it in? Thanks for the Help. BTW - I know it’s got be snugged if it’s leaking I just want to verify that I am doing it correctly.

Lata, Ark

It isnt adjustable. The only way to adjust it is to take it apart and change the spring inside.

If it is open at idle, it isnt a big deal. With a cut stock spring, they hold almost 40#s with NO boost on the backside.

Ya Lost me when you said "With a cut stock spring". IS that just the spring that they come with when you purchase them?
