Is this your first CAI? I find they kill some of the low end torque, but help the turbo breathe more top end.
I'd suggest putting your OEM kit back on and retesting, it may just be the characteristic of a CAI your experiencing... And hopefully your haven't dropped anything in the turbo fins.
Also check and double check any air leaks.
Can you run VCDS to check for errors and perhaps a Dyno... Rpm and MAF gs
