Actually I did find a leak but repairing made no difference.

Default What size MAF housing you using? (mm). Have you already replaced your MAF?
Also, what intake are you using? Open element? modded Stock box?

Is the car running poor, or you just figure you should be seeing considerably higher flow?

Default its fast (4.1 FATS) but CF's are high at 12 to 15. I'm guessing un-metered air getting..
in somewhere but I'm lost. Lower boost has little affect on the CF's either.

Default iirc you said you're running ~20psi? Most running 88mm MAF's are running higher boost levels than
that so i'm not too surprised at the lower MAF numbers.

Default recheck the seals and clamps.
go over each one you replaced b/c many leaks won't show until high psi.

also try cleaning your MAF. Remove sensor > put in baggie of isopropyl alcohol > shake shake shake > dry with condensed air > reinstall.
