FAQ

Who makes your tunes?

All of our tunes are built in-house by experienced diesel engineers — no outsourcing, no recycled files. Our team has hands-on experience with Cummins, Power Stroke, and Duramax platforms. They know these systems inside and out, and every tune is custom-built for your specific truck and setup. Clean, reliable, and dialed in.

WHY DO YOU OFFER FREE TUNING?

Because we do it ourselves. Our tunes are created in-house by engineers who know diesel — not farmed out to third parties. No middlemen, no generic files. Since it doesn't cost us extra to tailor each tune, we pass that value on to you. You get custom tuning at no additional charge. Simple as that.

How does the tuning work?

Our tunes are built for real truck owners — people who tow, haul, and put miles on their rig every single day. They're clean, reliable, and built in-house by engineers who actually know diesel. No racing gimmicks. Just solid performance, better throttle response, and improved fuel economy.
 

You give us the basics — VIN, year, make, model, and any mods — and we build a custom tune that fits your truck like a glove. Once it's loaded, say goodbye to DEF headaches and check engine lights. You'll be ready to tow with confidence. And it's all included with your kit. 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'll receive a confirmation email with a tracking number as soon as your order is dispatched. Delivery times may vary slightly due to carrier schedules or factors beyond our control.

DO YOU OFFER SUPPORT AFTER PURCHASE?

Absolutely. If you run into any issues with installation or tuning, our team is here to help. Reach out anytime at vip@trueamericandiesel.com and we'll get you sorted.
