I question if either of these are really necessary. Reason being, the S.A Alpine supercharger kit supposedly requires no modifications to the fuel system, however, a greater fuel delivery would be a must for these to operate correctly. This would have me believe that the stock fuel system would be adequate for the increased airflow.


I agree with Michael... from what you describe it sounds as though the intake diameter around the MAF is still the stock size, which should still read the velocity/amount of air entering the engine accurately. The modification you made sounds like a sort of velocity stack before and after the stock MAF. This setup could possibly be causing some turbulence around the MAF and confusing it a bit. Being that the MAF is a very delicate electronic, perhaps it was damaged during the modification process and all you need is a new stocker. But then again you say the stock 'ends' correct the issue???? At any rate, so long as turbulence is not an issue, I'd have to believe there's a more simple 'fix' to this than upgrading the fuel system and/or remapping the ECU, perhaps a resistor or capacitor or something to correct the [insufficient] signal from the MAF to the ECU... afterall, these are analog devices, correct?
