Because the AAM intakes have a metering orifice that is larger than the stock airbox. Thus, you have to scale the MAF table when tuning to restore your open-loop calibration to something normal.

Edit: my stupid tablet replaced 'oriface' (which was orifice misspelled, doh) with 'preface'.... stupid auto correct.

@cdoxp800: afaik with 2.75'' intakes MAF scaling is apparently necessary.

Humm. I have the Akuma intakes " 2.75" pipe and all we did was change the fuel multiplier.
Seems the tuner did it the really HARD way.
