What we do
Diesel performance & repair
Whether you need better response and more power, or your truck just isn’t running the way it should — this is the work coming through our shop.
Performance Work
Looking for better response, more power, or a truck that simply runs the way it should? We handle performance work on daily drivers and dedicated builds.
Tuning & Dyno
From work trucks to performance builds — if you want more out of your truck, let’s get it tuned. We tune for drivability and can put work on the dyno.
Ask About TuningEngine Overhauls & Builds
Complete overhauls that put life back in a tired engine. We can also build engines to suit your needs — including custom Cat MXS builds. Pricing depends on the job; ask us for a quote.
Fleet & Work Trucks
We keep commercial and work trucks moving — repairs, tunes, and leak work included. Big or small, the goal is the same: less downtime, more getting work done.
Diagnostics
A careful teardown tells the real story. We find the problem, explain what’s going on, and fix it right so you’re not guessing once the truck leaves the shop.
