That is why we should come right out and say, don't do it unless you want less power, slow building boost between shifts, and less drivability (in so many words). If you want to sacrifice all those things for a noise makers, than at least you were informed first...
slow building boost between shifts? support this. the rest is completely wrong, but i'm curious how you support that. barring a leaking BOV, there should be absolutely no difference in spooling between the factory bpv and any bov, as both should be in the same position under throttle--closed.
