Get more horsepower and torque from your 2017-2019 GM 2500HD/3500HD when you install a Chip, Module, or Programmer. There are some differences on how they work but all Chips, Modules, and Programmers will increase the performance of your vehicle. At the start of the diesel performance craze, performance Chip were the most common way to modify the programming but is now done by handheld tuners. Edge, SCT, Diablosport, and Superchips now offer Handheld Programmers that plug into the OBDII port and reflash the ECM with a proprietary tune. Dash-mounted tuners improve power and performance while also allowing you to monitor the engine and transmission's vitals.
Throttle Boosters and Calibration Devices are also available from XDP to improve your vehicle. OBII Splitters & Accessories from XDP allow you to plug multiple items into one OBDII port at the same time. Tuning Switches, mounts and knobs are also available. When different sized tires are mounted or the differential gears are changed, a Calibration Device is needed to calibrate the speedometer. A Throttle Booster amplifies the signal from your accelerator pedal to enhance the throttle response of your vehicle. Shop at XDP for a wide selection of Chip, Module, and Programmers to choose from to meet almost any budget.
