Default I'd like to see how these are...

It is an adjustable bpv/bov so you can have it full bov to full bpv depending on how much sound you want.

Default Stock now, trying Hyperboost this weekend, will log both

There is nothing obviously wrong with my stock diverters, I just want to see what the aftermarket DV's are like.

I'll try to post impressions and logs when the time comes.

Default Had 'em for a few months, didnt really notice TOO much of a diff

K04 Madness uses them (actually, the ones I sold him) and he loves them.

Let me know how the logs come out! thanks

Default BOV and MAF fuel injection

If you use a blow off valve, rather than a bypass, with mass air fuel injection it will change the air/fuel ratio. Under blow off conditions the engine will run richer than intended. The MAF sensor measured the air previously so it is injecting the according amount of fuel. However, that air has now been bled out of the intake system. It sounds cool, but probably will have worse performance than a bypass valve due to the A/F ratio being too rich. It also wouldn't be good for the catalysts either.

Default These are hybrid though...vent some and meters some.

I had 100% Blow off valves and yes, my car did run rich.

But these stealth are supposed to vent enough into the atmosphere to make a noise and recirculate the rest so the ECU sees the metered air. You might just run a TAD rich but not enough to throw codes and blow MAF's and CATS.

So, you just want the BOV noise?
