Turbo & Supercharger Service — UTV, Jeep & Diesel Trucks

We install, repair, replace, and upgrade turbo and supercharger systems across three platforms — this isn't a one-vehicle-line service. On the UTV/SXS side, we handle forced induction upgrades and service for Can-Am, Polaris, and Kawasaki machines that need real power for Sand Hollow dunes and desert riding.

For Jeep owners, we cover turbo upgrades, boost diagnostics, and repair on Wrangler and Gladiator turbo four-cylinder engines. And on the heavy-duty diesel side, we service and upgrade turbos on Duramax, Power Stroke, and Cummins platforms — turbo replacement, upgraded turbo installs, and related boost, wastegate, and charge-air diagnostics.

All forced induction work pairs directly with the ECU calibration and dyno verification covered above — added boost without a proper calibration and a verified power curve is a shortcut to broken parts. Expect meaningful horsepower and torque gains, verified on the dyno.
