VSE (Vin Specific Enterprises) specializes in diesel performance tuning, calibration, engineering, and parts for trucks and other vehicle platforms. The company emphasizes vehicle-specific calibration rather than generic, one-size-fits-all software, drawing on engineering expertise and dynamometer testing to develop and validate its products. Its team designs and manufactures components at a facility equipped with CNC machining and Dynojet and Mustang dynamometers.

VSE serves owners of GM Duramax, Ford Power Stroke, and Dodge/Ram Cummins vehicles, with tuning options organized by engine and model year. Its product range includes tuning devices and software, lift pumps, fuel filters, fuel system savers, cold air intakes, catch cans, CCV upgrade kits, intercoolers, turbo upgrades, and ECM repair services. The company also offers parts and equipment for other diesel applications, including commercial vehicles, agricultural tractors, semi-trucks, and motorcycles.

VSE supports daily drivers, fleet operators, towing professionals, independent dealers, and competitive racing teams. Customers can shop online, contact the company for technical support, or inquire about becoming a dealer.
