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.

How We Build the Advanced Custom Tune for You

When you get started with us, we’ll ask for a few details about your truck—like the VIN, make, model, and any unique setups. With that info, our tuning pros get to work, building a custom tune specifically for your truck. We’re talking about maximizing horsepower and torque and ditching those emissions system limits entirely. So, once it’s installed, no more dealing with DEF, no more annoying emissions lights popping up on your dash, and you’ll be able to tow some serious loads with confidence.

And here’s the best part: this whole process is all part of our service. No extra fees and we are the only company doing that.

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.

How are we able to provide tuning for free? The tuning map is created once and then adjusted based on each customer’s needs. For example, if a customer has made modifications in the past or wants something unique, we customize the tune accordingly. This process is the same regardless of where you buy the tune. As a company, we thought, “Why should we charge for something that doesn’t cost us much to produce each time?” It’s 100% possible to offer it for free, so why not do something different? Isn’t that the whole purpose of a company?

If a company is created just to replicate what already exists in the market without making any meaningful changes that benefit customers, why should it even exist? We believe in change, and we believe in providing exceptional value to our customers.

Included in this kit is the HP Tuner, which allows you to unlock the ECM on 2017–2023 Chevy/GMC Duramax L5P vehicles. This tuner comes with an ECM unlock tool, enabling you to unlock the ECM directly through the vehicle’s OBD-II port. This eliminates the need to purchase and install a pre-unlocked ECM, reducing costs and simplifying the installation and tuning process.

Don't panic! We will send you detailed instructions. Plus, if you have any questions or get stuck during the installation, we've got you covered. Don't forget you have unlimited access to our professional tuning technicians.
