By adding a Chip, module, or Programmer, to your 2004.5-2005 GM 2500HD/3500HD you can gain a significant increase in horsepower and torque. Performance Modules are designed to intercept and modify the outgoing signal between the ECM and the harness. Dash Mounted Tuners are designed to allow you to increase power levels and track engine and transmission vitals. Handheld Programmers are designed to reflash the ECM with tuning through the OBDII port. Performance Chips were a very popular way to enhance performance in older diesels, now handheld tuners deliver better performance on modern diesels. There are a few differences in how Chips, Modules, and Programmers work but they are all designed to enhance your vehicle's performance.
XDP offers a vast array of Throttle Boosters and Calibration Devices to improve your vehicle's performance. A Calibration Device can be useful when you add larger tires or change out the differential gears. Plug multiple devices into your OBDII port with the OBII Splitters & Accessories from XDP. Throttle Boosters enhance the signal from your accelerator pedal to improve the throttle response of your vehicle. Tuning Switches, mounts and knobs are also available for vehicles that have been tuned. Find the Chip, Module, and Programmer that suits your needs and budget at XDP.
