FAQ
Who makes your tunes?
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.
Why we offer free tuning?
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 the 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.
Whats your shipping times?
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.
