still didn't answer my question, i am talking about useing TOYOTA maf's, not mazda. so if they can rom tune the 2nd gen, then you can get a little more power out of a bigger maf from a n/a 7mge or the 5mge. i know the flapper maf's suck but i am still in the right so either go stand alone or get off the pot. now what about rom tuning 7mgte ecu's?
