Improved milage but when I had to go back to stock the milage stayed the same . Point is I am not sure if it did anthing . The one thing I will say is it keeps trans in gear loanger before shifting . Overall 3 stars .

Little to no gain

Reviewed By Patrick S (Methuen, MA) Reviewed for a 2001 Mercury Mountaineer —4/10/2007 4:37 AM

I have had the Jet PCM installed for a little over a week and noticed little to no gain in performance installation was easy but clean the s%#t out of the stock connections or it wont work. the only gain i noticed with the chip was when i changed the spark plugs to Bosch Platinum Ir Fusion. Modes done to suv 5.0 with cam/supercharger intake with 95mm mass airflow and magnaflow true dual side pipes best 1/4 13.9

Surprised at the ease of use.

Reviewed By Ken U (HUNTINGTON BEACH, CA) Reviewed for a 2015 Ford F-150 —2/10/2016 8:52 AM

Unit is pretty straight forward and works well. Had to play with the tire size twice before getting speedometer to read correctly. Note my tires from Manufacture said 34.6" and my final input into unit was 34.00" and the speedo is all good. Just remember to reset your vehicle back to stock if taking it to the auto shop if they're gonna plug into the OBD because if you don't it'll erase your settings and your hyper unit will no longer be operable for your vehicle..
