TNT Diesel Performance started in the spring of 2007. We were big in the local diesel sled pulling, drag racing scene so we purchased a mobile 248 Dynojet. We went around to lots of events so people could test their vehicles and tune them. We were doing work on trucks and getting before and after dyno results. After a few years we sold the dyno so we could focus more on doing engine and transmission work. From doing full engine rebuilds to just installing gauges, Specializing mainly in Dodge Cummins & Ford Powerstroke Engines and one on one customer relationships we take pride in all the work that comes through our doors.
