Chk my reply in the engine management sub forum

Was the MAF table rescaled? Did you change the MAF housing from stock? (Not familiar with the AVO kit plumbing)
The injectors were rescaled in the tune?

What are your c, d fuel trims?

We're the load ranges rescaled for the flow increase? Is that possible or do you have to rely on your D range to handle everything above it?

the maf housing is stock...it goes from the inlet of the turbo right near the radiator support and the filter right is off the maf housing...ill try to upload pics of the set up.
my tuner has all the info about the tune...i dont know much abou tuning ive just been watching him tune it..
i know when he first tried to tune it he didnt have the correct ROM for it since its not wrx or a sti and alot of the options arnt avalible for him to access in his lap top..
im pretty sure the injectors were rescaled
ill try to get the fuel trims tommorrow
