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. SCT, Diablosport, and Superchips are Hand Held Programmers that plug into the OBDII port and reflash the ECM with proprietary tune. At the start of the diesel performance craze, performance Chip were the most common way to modify the programming but is now done by hand held tuners. Dash-mounted tuners improve power and performance while also allowing you to monitor the engine and transmission's vitals. An Edge Juice With Attitude or Banks Six-Gun are Performance Modules that intercept and modify the outgoing signal between the ECM and the harness.
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. For vehicles that have been custom tuned, tuning switches, mounts, and knobs are available. A Throttle Booster from BD-Power or GDP Tuning 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 or Hypertech Calibration Device is used to correct the speedometer when different sized tires are installed, or the differential gears have been changed.
