If you have a highly modified 1985-1991 TPI Corvette, then this is the sensor for you. This unit is the only mass airflow sensor that features fully adjustable calibration, so high lift cams, big valves and larger intakes are no longer a tuning problem for performance enthusiasts. The sensor provides up to 30% more airflow than the standard OEM unit, and you don't have to tear out the screen! The Granatelli Motor Sports Adjustable Mass Airflow Sensors come equipped with a calibration screw builtright in. Engine running too rich or too lean? No problem!! Just whip out a screwdriver, give the calibration screw a twist and WHAM!!, problem solved. No other mass airflow sensor available gives you this much control. Installation occurs in 10-15minutes using basic hand tools. Each system is backed by a limited 90-day warranty.
