Are the Autothority chips that you have designed for a MAF unit or are they stage II chips? If they are not from a MAF kit,,you will probably need to send them back to APE and get them reprogrammed....prom MAF 75mm unit?? Pro Flow? Did you get your turbo, injectors, and wastegate from Tim? If so, why didn't you get his MAF?

IF the MAF was already installed on the car then you need to keep those chips..there is a difference in the chips(stage II) and the way they are programmed. MAF kits have their own chips that usually come with the entire kit.
