🚨 BIG NEWS — SOMETHING IS COMING TO 4W DIESEL! 🚨
We have kept this one quiet for a while, but it is finally time to let the news out…
4W Diesel Injector Service is getting a SuperFlow dyno!
The concrete removal has started, and we are one step closer to having an in-house dyno installed at the shop. This will give us the ability to put trucks to the test, verify results, and take our diesel performance and diagnostic capabilities to the next level.
Whether your truck is a daily driver, a work truck, a tow rig, or a full-on performance build, we are excited to bring something new to the diesel community in Northwest Arkansas.
This is just the beginning. Stay tuned for build updates, installation progress, and the first trucks on the rollers.
Who wants to be one of the first trucks on the dyno? Comment below or message us!
