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 also track engine and transmission vitals. Hand Held Programmers are designed to reflash the ECM with custom tuning through the OBDII port. Performance Chips were a very popular way to enhance performance in older diesels, now hand held 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.
