🔧🚗 Some days in the shop, diagnostics feel more like detective work… and other days the vehicle practically tells us what’s wrong! 😂

Recently we’ve had:
🌪️ An air filter that decided it wanted to take a trip through the intake system.
💥 A customer chasing down a mysterious clunk that turned out to be an engine trying to jump out from under the hood!

No matter how strange, simple, loud, or complicated the problem may be, we’re ready for the challenge. 🛠️💪

A huge THANK YOU to all of our customers for trusting TNT Diesel Performance & Repair with your vehicles. Your support means everything to us, and we’re proud to help keep your trucks, cars, and equipment on the road and working hard. 🚛🚜🚗

Pulled this thing from the bushes last Thursday! With known blown head gaskets, we elected to just throw a set of batteries from the core pile in it and a saucy tune up and take it pulling! With one goal in mind, BLOW IT UP😎

364.42 for a solid second place against one of our customers Nicholas Ebert💪💪💪

TNT taking home 1st and 2nd is always good news!

Unfortunately we didn’t blow it up, so it looks like we will be hitting the pulls in Potosi in June to see if we can make it give up there😂😂😂

Thanks again to Madison County Pullers Association for putting on a BANGER truck pull! You all went above and beyond in every aspect and we can’t wait to be apart of the next one👏👏👏👏

Rolling into the weekend the right way. 🔥

Knocked out a Hamilton flat tappet conversion paired up with a Banks Monster intake—this setup is all about reliability, airflow, and getting these trucks breathing and running the way they should. 💨

No shortcuts, no half work—just clean installs and parts that perform.

At TNT Diesel Performance And Repair we’re here for the big power builds and the upgrades that keep your truck alive for the long haul.

If your valvetrain’s questionable or you’re still choking that motor with stock airflow… you already know what to do.
