Important Information about the Tune

How does tuning work?

Tuning involves adjusting your vehicle's engine control unit (ECU) to enhance performance, fuel efficiency, or other preferences. It can modify the way your engine performs by changing settings like fuel/air ratios, ignition timing, and turbo pressure.

What does the tuning device do?

The tuning device connects to your vehicle's OBD-II port and communicates with the ECU. It allows you to upload custom settings (or “tunes”) to adjust your engine's performance. These devices also allow for data logging, diagnostics, and monitoring of engine performance.

What is the process for getting a custom tune?

  1. Initial Setup: After purchasing a device, you’ll connect it to your vehicle and send us the information it gathers.
  2.  Creation of Advance Tune Customization: Using that data, we create an advanced custom tune that significantly increases power while maintaining efficiency. Our focus is on delivering enhanced performance without excessive smoke or burning too much fuel.
  3. Installation: We’ll send the custom file back to you, and you can load it onto your device to upload it into your ECU.

Why is there a price difference in tuning?

The price reflects the level of customization involved. Unlike generic tunes, which are pre-made and may not be optimized for your specific vehicle, our custom tunes are tailored to your vehicle’s unique configuration and your preferences. This requires expert knowledge, detailed analysis of your vehicle's data, and crafting a solution that balances performance, safety, and durability.

What do you provide besides the tune?

We offer ongoing support to ensure the tune works perfectly for your vehicle. This includes revisions based on your feedback or changes to your vehicle. Plus, our service includes personalized customer care.

Is tuning safe for my vehicle?

Yes, when done properly. Our custom tunes are designed to be safe and reliable. We carefully balance performance improvements with engine longevity to ensure that the tuning process doesn’t cause harm to your engine or other components.

Included in this kit is the GDP Commander Tuner, which allows you to unlock the ECM on 2017–2023 Chevy/GMC Duramax L5P vehicles.

This tuner eliminates the need to purchase and install a pre-unlocked ECM, as it provides the functionality to unlock the ECM directly through the vehicle’s OBD-II port. This significantly reduces cost and makes the installation and tuning process simpler.
