When you install a Chip, module, or Programmer, your 1982-2000 GM 2500HD/3500HD will produce more horsepower and torque. There are some differences on how they work but all Chips, Modules and Programmers will increase the performance of your vehicle. Edge, Banks, SCT, Diablosport, and Superchips are Handheld Programmers that plug into the OBDII port and reflash the ECM with proprietary tune. At the start of the diesel performance craze, performance Chips were the most common way to modify the programming but is now done by handheld tuners. Dash-mounted tuners improve power and performance while also allowing you to monitor the engine and transmission's vitals.
Throttle Booster 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. Switches, mounts, and knobs are also available. A Throttle Booster amplifies the signal from your accelerator pedal to enhance the throttle response of your vehicle. Choose from a wide range of Chip, Module, and Programmer at XDP to fit practically any budget. A Calibration Device from Superchips can be used to correct the speedometer when different sized tires are installed, or the differential gears have been changed.
