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

Works as expected

Reviewed By Wayne B (PEORIA, IL) Reviewed for a 2013 Jeep Wrangler —9/21/2016 6:43 PM

Intuitive interface. Easy to use. Made changes to tire size. Plan on a regear in the future. Was able to turn off TPMS. I was hoping to be able to create a increased idle setting for winching, but you must have the tuner plugged in when you want to increase engine speed. Did take a good 30 mins to flash on a new 87 octane tune. Did notice a little increase in throttle response, but not blazing.

Nice addition without going overboard.

Reviewed By Trent M (Ellensburg, WA) Reviewed for a 2008 Ford F-350 —9/21/2016 9:16 AM

This is a nice option if you want to tweak your engine performance. It is easy to use and doesn't required routing wiring and making connections. In the time I've been using it it has lived up to my expectations.
