It is CRITICAL that anyone installing ANY supercharger kit inspect & test and/or replace their mass-air sensor element. We've seen that the mass air sensor element can get very dirty(remember in the lotus much dirtier air hits the intake than a car with a front intake.) and this dirt will cause the mass-air sensor to read low(Its a fairly linear change). Aftermarket intakes, higher mileage cars, and cars operated in dustier or dirtier conditions are even more prone to this.
This will cause the ECU to think more air is entering the engine than reality you will have a potentially dangerous lean condition!

You can test the mass-air sensor with a scan tool by having someone monitoring the mass-air sensor while you drive WOT in second gear. You should see 225-230grams/sec at above 8200rpms. If you see much less than this you should replace your mass-air sensor element. These new mass-air elements may not survive harsh chemical cleaning and should just be replaced.

Fred,

What are your thoughts on using CRC Mass Air Flow Sensor Cleaner? I've used their products in the past (brake cleaner, carb cleaner etc...) with no issues.
