JDM Engineering

Converting your 1999 & 2000 Lightning to a 90mm MAF (Mass Air Flow Meter) permits your truck to produce more horsepower while still keeping MAF sensor voltage within range (0.80 to 5.00 volts). The horsepower gains from our Street Performance Programs cause the stock 80mm MAF to hit the maximum 5.00 volts by 4,600 RPM. To handle horsepower production beyond 360 HP at the rear wheels, the 90mm MAF is recommended. This installation requires the use of a PCM chip, such as JDM's Dual Program PCM Flip Chip .If you already have a JDM or any Superchips chip, we will reburn it to work with your new MAF at no cost. When combined with one of our chips, you will see approx. 6 to 8 tenths better ETs in the quarter mile.
