Lots of questions need to be answer but most of all, it needs to be proven by an unbois company (third party). Not only Dyno tested but track tested. Also the dollar for HP radio should determine the valve, just compare with superchargers or turbo's. In regards to power band requirements (peek) delsolvtec said, is not correct, exspecially for road racing and auto-x.
You want lower RPM torque and HP for turns and curves, peek HP is not where its at, in fact your hitting peek for a very short time. my 2 cents.....
