2011-2014 Jeep Grand Cherokee 3.6L Performance Tune

​The 2011-2014 Jeep Grand Cherokee is one of the top SUVs on the market, and it’s base model 3.6L Pentastar V6 makes it enjoyable to drive. When Jeep manufactured the 3.6L they had a lot of factors to consider, one of which was a tough economy that created budget conscious buyers. As a result the 3.6L Pentastar came tuned from the factory optimized only for 87 octane fuel.

The RPM-Motorsports ECU Tune re-calibrates many tables within the tune to deliver more precise power, and a more responsive engine. By rewriting the timing advance tables to take advantage of 91 or 93 octane fuels, an enormous amount of top end power can be increased over stock. What you end up with is a more lively V6 that provides better acceleration and response at any vehicle speed.
