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

Love It!!!

Reviewed By David S (VIRGINIA BEACH, VA) Reviewed for a 2007 Toyota Tundra —2/17/2017 5:54 AM

Bought it cause I put 35's on my Tundra and I was about 5mph off comparing to GPS. Also noticed shift points were off along with gas mileage. This calibrator not only allows you to fine tune the speedometer but it also brings the shift points back to factory settings. I am now back to 18+mpg on highway and 13-14 aound town and I am heavy on the right foot. Easy install, just make sure to zip tie to prevent rattles behind the dash. Highly recommend.
