HELP! with my FMIC

[wicked]

I just finished my FMIC and now I have a problem.

If I boost the let go it pulses rather violently.I can't find any leaks,the BOV is atmospheric.
I know the car will stall with this BOV but it's only temporary.



But the pulse is bad I can hear it in the intake like a surge but I don't know what is causing it.

it probably is your BOV causing this and your ECU is trying not to let this happen...what kind of BOV do you have?

[wicked]

it's a turbo xs type-s.I've been running it on my turbohoses pipes for a few months with no problem.

its cuz the bov is prob too tight , im sure you are runnign it tight so you dont stall as easy , and a possible leak. ( leak will piss some air while its trying to open )
if it was recirculated i would tell you to loosen it up see if it helps but it will just make you stall like a freak if your venting

I had a suspiciain,and you were right.I couldn't lossen it enough so I found a spring out of an old munsi tranny that was about the same rate but 3/4 of an inch shorter.work great now but yeah stalling like a freak.
oh well,I just went and ordered a HKS ssqv with rec. and the purple insert.I WILL make this work!
