Played around with it today a little more. It seems ive lost a little low end acceleration. Idle to around 2-3k seems slower or more slugish but once it gets past that i feel a little more gain.

Not really what i wanted, i wanted more bottom end but im going to leave it because i think im going to install cams and a larger TB so maybe that will help?

I understand why they are there now, its a cool idea. When your at a lower RPM the flaps close down and force the air threw the smaller closed off opening i dont think it actually tumbles the air as much as it increases the velocity and i think thats where it helps.

I wouldnt recommend doing this. I think the stock intake is best left like it is so far.
It's not important to win, it's important to make the other guy lose.
