Stealth Module | #1 Diesel Performance Part for Cummins, Powerstroke, Duramax - Different than a traditional diesel tuner

Why choose Stealth?

Nothing is worse than spending hard earned money on a diesel pickup truck that doesn't drive like you think it should for the advertised power it's capable of. Poor responsiveness, sluggish taking off, missing that low end power you need in every day driving situations... sound familiar? Whether it's a Cummins, Powerstroke, or Duramax, we know what you mean. We get it!

We designed and tested our modules for real world abuse, real world driving situations, and extreme temperatures. We’ve worked hard to give you a product that provides additional power where you need it. Best part is the peace of mind knowing your stock safety parameters are still in place.

Improve Drivability. Smooth and Predictable Power.

We are a small team that works hard to provide not only an exceptional product but the best customer service around. Give us a call and let's get your truck what it deserves.
