Diesel Spec – North America’s Leader In Truck Tuning
Diesel Spec is the largest performance shop for heavy-duty trucks in North America with 485 retailers in the USA and Canada that perform over 5,000 truck tunes each year.
Tuning is the process of fine tuning the software in the truck’s ECM module, with the end result of creating more power, greater response and less fuel consumption. Diesel Spec offers 4 types of tunes:
The High Performance tune is the choice for truck pulls and racing. The Performance Tune provides extra power for heavy loads and pulling mountains. The Fuel Economy tune does exactly what its name implies, and the Off-Highway tune eliminates horsepower robbing add-ons. Truck owners are urged to check their state laws, however before having an off-road tune performed. The tune itself can be done at any of Diesel Spec’s 485 retailers in about 2 hours. The customer decides which type of tune they would like performed, then a tuning module is plugged into the truck’s ECM and the tune is performed remotely from Diesel Spec’s Montreal, Canada headquarters. Each tune carries a 30-day satisfaction guaranteed warranty and a one year reflash in case the ECM is reset at a dealer. Both warranties are included in the price of the tune. Most customers experience a 5-20% (about ½ mile per gallon) gain in fuel economy. Tunes are available for nearly every engine, including: CAT, Cummins, Detroit, Isuzu, Mercedes, PACCAR, AND MaxxForce. Updates are available for all modern engine versions. Diesel Spec also does tuning for farm tractors and off-road equipment.
Diesel Spec sells high performance parts including turbos, exhaust manifolds, intake manifolds and crank dampers. The company has two dynometers at their five million dollar facility in Montreal for their customer’s convenience.
