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.
