VSE | Precision Diesel Tuning, Software & High-Performance Parts

Engineered for Precision. Calibrated for Life. VSE brings the zero-tolerance precision of nuclear engineering to high-performance automotive calibration. Founded by Tom, a licensed Senior Nuclear Reactor Operator with degrees in Mechanical and Nuclear Engineering, VSE blends rigorous data discipline with advanced powertrain mechanics. We don't flash generic, one-size-fits-all software. Because an engine’s volumetric efficiency and internal tolerances change over time, we calibrate for your specific vehicle.

Operating from a state-of-the-art facility, our team of over 20 licensed engineers, developers, and machinists designs, manufactures, and validates emissions-compliant components. Utilizing Haas and Centroid CNC machining alongside Dynojet and Mustang Dynamometers, we optimize nearly any vehicle platform on the market: American Muscle & Trucks: GM (Duramax/LS/LT), Ford (Power Stroke), and Dodge/Ram Cummins. Commercial Vehicles, Toyota, Nissan, semi-trucks, agricultural tractors, and motorcycles. Backed by industry-leading technical support and internal shipping operations, we deliver total operational satisfaction for: Daily Drivers & Fleet Owners seeking optimized fuel efficiency. Hotshot Haulers needing robust tow rig calibrations. Independent Dealers expanding performance offerings. Competitive Race Teams building dedicated drag or sled-pull vehicles. Our development pipeline relies on industry-leading software and hardware providers: WinOLS, HP Tuners, EFI Live, EZ Lynk, Alientech, Dimsport and Bflash.Hard Parts & Systems: SoCal Diesel, Exergy Performance, Flo~Pro, MBRP Exhaust, and S&B Filters.
