As Luigi said, low end = usable power on the street so I'm once again considering the M370 manifold since, from the dyno sheets I've seen, it seems bring up that low end at the expense of a little high end.
Not to mention Birdman has that youtube video with M370, Berk HFCs, and FI CBE and his car sounds ridiculously good.

I think it's time for you to have your car tuned. The exhaust, hfc/tp and CAI gain HP overall. But mainly the powerband is at high end. And you will feel sluggish at low/mid end. A fine tune don't necessary gain you much peak power but it definitely can correct your A/F ratio from running lean or rich. And you will definitely gain a lot mid range torque thus you will feel the car accelerates effortless.
