you underestimate the stalling my friend... it is possible to happen ANYTIME you stop, if you dont have ur foot over accelerator as you brake your f**ked, trust me lol.
It'll hunt for AFR like a c**t, go up and down the revs like crazy then if u dont balance it out with the accelerator ur stuffed, can happen anywhere, even while you are moving downhill, put it in to nuetral to double clutch cause ur synchros are screwed then the car stalls as you are rolling at 70km/h...
you need a retune if you remove the stock bov, and then the new bov u get needs to be tuned too...
ADAM, a vent to atmo BOV is one that VENTS TO ATMOSPHERE, ie, has a little trumpet or filter or whatever is aftermarket these days are pretty much all vent to atmosphere, thats the valve that creates the phshhhhhhht noise. k thnx bye lol.
