I think it's the intake. The Skunk2 Powerbox CAI is HUGE. I have the restrictor that it comes with in place to keep the air around the stock MAF close to stock, but the intake piping that is after the MAF is still huge. I'm no professional, so don't quote me, but IMO I don't think the air velocity is not able to keep up at a higher RPM because of the large piping. My reasoning doesn't make sense after I think about it, but I do still believe the problem is/was the intake. Anyone with higher knowledge about that may pleasantly tell me otherwise, I'd love to learn.
I've seen more and more club members switch back to the stock air box and drop in solution and make more power than whatever CAI they had. Mine's not bad for now, but when I eventually upgrade to the flex fuel ACE tune, I'll put the stock box back on and see what Delicious thinks.
The Grams 72mm throttle body, again not a professional, but I believe it's really only affecting the throttle response, which is amazing btw.
