Bov releasing late!!!!

The pssshhh sound comes seconds after I release the throttle. Because of this, when I shift really fast, you dont even hear the pssshhh. Seems as if the air just gets recirculated rather then releasing. Anybody have this happen or have any clue why this is happening?

your spring is too stiff... depending on the bov you need to get a softer spring or adjust the bov to make it softer.

I have no clue... it's whatever UR ships. It worked well both with and without PROcede. I think that they posted the spring weight... I'll see if I can find the specs.

{edit} it's the -11 spring.

I think I have the 11 lb spring. He was nice enough to send me a 9lb spring, so ima test that out and see if it works. I know Hyperm3 is not too happy with his product either.

Is that the only reason why the release would be late?

are you talking about shifting at like 6k rpms? if so its normal for it to not happen all the time

instead of shifting try going to 6 k and just taking your foot totally off the throttle (without even touching the clutch) if it still not going then maybe you have an issue
