When you install a Chip, module, or Programmer, your 2007-2008 Jeep Grand Cherokee will produce more horsepower and torque. Even though there are some differences in how they work, all Chips, Modules, and Programmers will improve your vehicle's performance. Dash-mounted tuners improve power and performance while also allowing you to monitor the engine and transmission's vitals. Performance Chip were the most common way to modify the programming at the dawn of the diesel performance craze but is now done by hand held programmers. Performance Modules such as an Edge Juice With Attitude or Banks Six-Gun intercepts and modifies the outgoing signal between the ECM and the harness. SCT, Diablosport, and Superchips are Hand Held Programmers that plug into the OBDII port and reflash the ECM with proprietary tune.
Throttle Booster and Calibration Devices are also available from XDP to improve your vehicle. Shop at XDP for a vast selection Chip, module, and Programmer to choose from to meet almost any budget. Tuning Switches, mounts and knobs are available for vehicles that have been custom tuned. OBII Splitters & Accessories from XDP allow you to plug multiple items into one OBDII port at the same time. A Calibration Device from Superchips or Hypertech Calibration Device is used to correct the speedometer when different sized tires are installed, or the differential gears have been changed. A Throttle Booster from BD-Power or GDP Tuning will boost the signal from your accelerator pedal, improving your vehicle's throttle response.
