Those spicy Shift On The Fly tunes give folks a few more options and a little more horsepower than some of their trucks can handle. This one came in for some upgrades and after giving fair warning that anything over tune 1 would roast it, here it is back once again. 3 days into driving it and the clutches have exited the chat… Here’s how we’re making sure it won’t happen again!

The diesel industry has become a bit notorious for its lack of quality control, and after this incident, we’re wondering if even the biggest names in the industry are starting to suffer from this dilemma!! Have you guys had a similar experience to this? Who do you think should pay for mistakes like this? Let us know in the comments below…

They wrote an article about the 7.3 folks. 😂 Be sure to go check it out.

They filled the tank with everything but diesel, changed the oil with the engine running, and shot so much nitrous into the intake—but it hasn't quit yet. https://trib.al/tMXBFRW

To make big horsepower, you need a LOT of fuel. For us, there’s only one way to flow that fuel, and that’s with this competition FASS Fuel Systems 540 GPH pump!! Big shout out to Fass for helping us get the fuel we need to reach our 2,000hp goals for our 6.4 Powerstroke race truck!! Can’t wait to get her ripping down the track again.
