Boost controllers and a/f ratio...

[98spydert]

I've been doing boost leak tests lately tryiny to track down a boost leak at my throttle body. While doing this I found that the boost controller leaks out a good amount of air(it's supposed to I know). My question is, if you are running your boost source for the boost controller from the bov line or any other post-MAF line, is that air that's vented or blead off by the boost controller enough to impact a/f ratio or, more importantly, performance?

Not significantly. If you're worried about it, then set up a gm maft blow through set up and run the boost controller between your turbo outlet elbow and wastegate. That way any spent air is accounted for.

I already have a GM MAF set up, it's in my profile.
