All of our tunes are made in-house by top-tier engineers—no outsourcing, no third-party files. These are guys who’ve worked with the big names: Cummins, Power Stroke, and Duramax. They know these systems inside and out, and they build every tune to be clean, reliable, and tailored to your setup.

Our tunes are made in-house by top engineers who’ve worked with Cummins, Duramax, and Power Stroke. No third parties, no reused files—just custom, high-quality tuning built for your setup. It doesn’t cost us much to adjust per vehicle, so why charge you? Simple as that.

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.

Trans tuning is not included in this package, but we do offer it as an add-on. It's an additional $1300 and includes the TCM unlock. Reach out to us by phone or email, and we’ll be happy to send you a quote.
