Diesel Performance Chips vs. ECU Remapping

If you are looking for a way to improve your diesel truck’s power capabilities, you are likely debating between performance chips and Engine Control Unit (ECU) remapping. To help guide you in your thought process, read how diesel performance chips and ECU remapping differ. These points will reveal the important distinctions that may help in your decision.

What Is ECU Remapping?

ECU remapping entails changing or rewriting the vehicle’s software inside the ECU. The rewriting specifically targets ways to improve the pickup’s torque, power, and overall performance. ECU remaps increase the vehicle’s performance and also account for all aftermarket modifications, such as exhaust, snorkels, and fuel tanks.

What Is Chipping?

Chip tuning intercepts data received and sent by the ECU, as opposed to altering the ECU itself. Chips alter a truck’s fuel rail pressure, thereby atomizing each injector and their air to fuel ratio. By increasing the combustion, chips make the engine run more efficiently.

Using a chip, you can add more torque lower in the rev range of the vehicle, which means the truck does not need to work as hard as before. As a result, you maximize the energy output and set free the torque and power that was lost during the vehicle’s factory programming.

Which One Should You Choose?

If you are choosing between the two, it is vital to understand how diesel performance chips and ECU remapping differ. By comparing their advantages and disadvantages, you can make a more informed decision about which is right for your truck.


  • Since remapping overwrites the ECU software, it may void your manufacturer’s warranty.
  • Chip tunings are installed downstream of the engine’s Central Processing Unit (CPU), and therefore do not change the parameters already created by the ECU. They may not void your warranty.

Permanent or Removable

  • Remaps are permanent installations.
  • Chip tunings can be turned off and on. They can be disconnected entirely.


  • Most remaps require a trip to the nearest tuning shop. Your vehicle will be out of commission while technicians get the remapping prepared.
  • A chip gets plugged directly into the common rail. As soon as it is fitted, it automatically sets to the highest performance mode.
