You don't even have to get an aftermarket BOV. Just stick that duck call up your ass and fart. The hard part is timing the fart with your upshift, and of course there is also the smell issue.
Coming back to reality, I think the undercurrent of the responses is that runnign VTA on a MAF engine is a bad idea.
There's another long thread here (at least one) with the raging debate. IMHO, it's just bad for these engines. The last thing in the world you want is for your engine to run even richer, especially when you upshift and hit the engine with a full load right after having dumped some of the precious already metered oxygen out through your noise maker rather than into the engine where it belongs and where the ECU thinks it is going.
One member of this board has personal knowledge that VTA users consistently dynoed lower that recirc cars with the same mods on the same dyno and that most of those guys saw the light and switched to recirc mode.
Returning to the humorous side, it's better to stick the duck call up your ass and fart that lose the power and run even richer than we already do, IMHO.
