Happy Birthday, Travis!🎉
Today we’re celebrating the man behind Powerhouse Diesel- a business built not only on hard work, dedication, and determination, but on the kind of character that makes people proud to know you.

Travis, your commitment to your customers, your team, your family, and everyone around you does not go unnoticed. You’ve built more than a business, you’ve built a community, and something you can truly be proud of.

We hope today reminds you just how appreciated you are and how many people are thankful to have you around. May this next year bring you continued success, good health, happiness, and plenty of opportunities to slow down and enjoy the fruits of all your hard work.

From all of us at Powerhouse Diesel, We hope you have an amazing birthday!

Cheers to you!🔧🎉

Real customers. Real results. 🔧⭐⭐⭐⭐⭐

CP4 pump failure? Handled. Extra issues found and fixed along the way? Handled. That’s what you get when you bring your truck to a team that actually knows Cummins, Duramax, and Powerstroke platforms inside and out.

Terry, Bradon, and Micheal trusted us with their trucks and walked away five star happy. Your truck deserves the same treatment.

Your 6.0 is leaving power on the table and you know it.

Twelve years of R&D went into our calibrations. Farm truck, tow rig, race truck, we’ve got a file for it. Clean power that doesn’t gr***de your engine.

We specialize in sled pulling, drag racing, compound setups, and anything else custom you can dream up. We’re also one of only three shops supported by Warren Diesel for IPR/ICP sensor setups.

Then there’s the FICM. Everybody skips it. That’s the mistake. ECM tuning asks for fuel, the FICM decides what you actually get. Tune both and the truck wakes up. Better cold starts, sharper throttle, real gains you feel the second you touch the pedal.

Send us your FICM for a bench flash or run it yourself if you’ve got an MVPI.

Stop guessing. Get it tuned right.

Turns out our crew can do more than turn wrenches. We’ve got some real hidden talents around this shop.

Today, Tennessee lost a true legend.

Dolly Parton wasn’t just the Queen of Country Music — she was a Tennessee icon, a storyteller, a businesswoman, and a woman who never forgot where she came from.

From the mountains of East Tennessee to stages around the world, Dolly left a mark that will never fade. Her music, kindness, humor, and heart will live on for generations

Rest easy Dolly, We will keep the trucks running & 9 to 5 playing🧡🔧
