After your purchase, you will receive a form that you have to fill out with the necessary info of your truck, like VIN, make, and year. This way, we can preload your custom tune on the device so you receive it already preloaded. You just have to plug it in, and you’re all set.

We process and ship all orders within 1-2 business days to all U.S. states. Once shipped, delivery typically takes 5-8 business days, depending on your location.

You will receive a confirmation email with a tracking number once your order has been dispatched. Please note that delivery times may vary slightly due to carrier schedules or external factors beyond our control.

Our tunes are made in-house by people who have worked with Cummins. We build and support the tuning for your truck ourselves.

We build our tunes in-house, so we control the tuning costs. Different tunes and tuning adjustments are free with your tuning purchase.

How does tuning work?

Our tunes are built for real truck owners—people who tow, haul, or drive their rig every day. They're clean, reliable, and built in-house by pros who know what they're doing. No racing nonsense, just solid performance and better fuel economy.


You give us the basics (VIN, make, model, and any mods), and we build a custom tune that fits your truck like a glove. Once it’s in, say goodbye to DEF headaches and warning lights. You’ll be ready to tow with confidence—and it’s all included, no extra fees.


What Does the Device Do?

The tuner plugs into your OBD-II port and loads your custom tune. It also lets you check performance, run diagnostics, and keep your truck dialed in.

Transmission tuning is included for 68 RFE. This tune will optimize shift points and line pressure for long term reliability of your transmission. It will also result in better fuel economy.

With the shift-on-the-fly cable included in the bundle, you'll be able to switch between 4 power levels in real time.
