Default Car is ridiculously slow. Help!

My car has been seriously down on power lately. I know it's a 2.5i, but I can clearly tell something's wrong, it's painfully slower than normal. When I take it to redline, that makes no power. It goes fastest shifting at 2500 rpms . I did some logging with romraider and peak airflow was 68g/s (should be 110-130). Also, my calculated engine load starts around 1 g/rev and steadily falls to .7. I would post the logs, but I don't know how.

Mods: AVO intake panel, LWCP, OBX header w/ magnaflow catback, phenolic intake manifold spacers, open source tune on 91 octane.

What I've checked: No restrictions in intake/ exhaust, MAF sensor is good, spark plugs were done a year back, no knock/ misfires in data log, don't think it's a vac. leak because idle is perfectly normal.

Any ideas? I've been dying to figure this out.
