The 01-04 Lightning vehicles were given a higher horsepower rating for these years (versus the 99-00 models) due to the fact that Ford revised the computer program to deliver a very lean 13:1 air/fuel ratio from the factory. The 99-00 Lightnings came from the factory with a much richer 11:1 air/fuel ratio. The ideal air/fuel ratio for a supercharged vehicle is typically 12.25:1, depending on the timing level and octane quality of the fuel.

Track testing of this package on a completely stock 2002 Lightning dropped the 1/8th mile ET's by .57 seconds with a trap increase of 4.5 MPH. The 95mm mass airflow package is available separately, but dyno testing has shown a larger gain is achieved from the air meter with the tune installed (17HP) than without (7-10HP). Other tunes may be used with this air meter package, but we can not guarantee an exact level of performance when using them with the 95mm system.
