i think the wideband o2 sensor and piggyback would fix that. dunno about the resistor; its typically used to reduce the voltage signal so that the ecu thinks there is less air and reduces fuel (resistor in parallel to the maf, where the maf operates as a variable resistor in a voltage divider circuit - no airflow = no resistance and 0 volts, max airflow = large resistance and 5 volts). where the ecu usually runs rich at wot, the leaning out of the fuel pulls it closer to stoichiometric, increases fuel economy, increases power (but with the risk of potential engine damage due to heating, detonation with low octane fuel, etc.). we want to increase the voltage signal, as the larger maf housing is making the ecu think there is less air than there really is. we could put a resistor in series with the maf to accomplish this, but then the ecu would think that there is airflow when there isn't and have a tantrum. i think.
