The stock intake for the Perrin rotated kit is a Big MAF (and it sucks). They also offer a replacement IC pipe that has a blow-thru set-up incorporated.
Mike at GST has tuned many blow thrus using the Perrin blow-thru tube and using weld-on MAF flanges that he bought from me. But yeah, it is tough to tune BTM for driveability.
