nice upgrade for a 3.7 jeep!

Reviewed By Steven W (Rensselaer, NY) Reviewed for a 2006 Jeep Grand Cherokee —10/31/2016 2:10 PM

I bought this for my 06 jeep grand cherokee with the 3.7 V6. it has a 2 in lift and bigger tires (31's, i didnt want to go too big since its my daily). i bought the programmer mainly for tire size calibration for my speedometer, but i was pleasantly surprised by the performance increase from the tunes. great power increase across the RPM range, throttle response is instant (i also have an injen cold air intake), its no race car but its a nice addition. MPG's increased also. only con is price

Superchips tuner

Reviewed By Danny G (farmington, IL) Reviewed for a 2013 GMC Sierra —3/22/2017 3:31 PM

This is my second superchips tuner I have purchased, one for a 2009 Sierra and this one for my 2013 Sierra. Combine this tuner with a good cat back exhaust and cold air intake setup and you can tune your truck to run the way you want. Very happy with the ease of use when connected and making changes. No going to the dealer when installing larger tires to get the speedometer reset.
