If you are looking for a way to improve the horsepower from your engine as well as improve your throttle response, the Jeep Grand Cherokee performance chip is for you. This component doesn’t increase power; instead it helps you to utilize what you already have. Your vehicle is already equipped with an Electronic Control Unit (ECU).

The ECU’s job is to maintain an appropriate fuel/oxygen ratio. By making sure the fuel mix is not to rich or not rich enough, a very good balance of power and fuel efficiency is maintained.

The ECU is set to maintain a 14.7/1 ratio. A Jeep Grand Cherokee performance chip modifies the signals that are being read by the ECU and then gives an adjustment to the fuel curve. Its job is to create the optimal fuel/oxygen ratio that will give you extra horsepower. This ratio setting could vary between 12/1 and 14.7/1. As it increases power, this chip will decrease your fuel economy by half a mile per gallon at most. That is a small price to pay for a performance increase. By installing a Jeep Grand Cherokee performance chip you will not at all interfere with any factory warranty. It also works well with any other minor performance upgrades you may have already made like cold air intakes, exhaust headers, or high flow air filters. Feel the difference it can make on your vehicle. We will meet or beat any competitor’s price for the exact same part.We also offer a quality guarantee on all products sold.
