Hi munro, according to me if the MAF you wear, you simply will reduce? the performance of the engine in dodo proportional to its wear and tear! Let me explain: since the map of the fumosit? limit? the quantity? gas injected (IQ) as a function of the quantity? of the intake air, so if the MAF reading? a deal? the air in the lower entrance, the logic from the ecu not to? reduce the amount? fuel injected and consequently reducing the performance! Or at least this ? as I think about the logic...![]()
