Diesel Spec – North America’s Leader In Truck Tuning
Diesel Spec is the largest performance shop for heavy-duty trucks in North America with over 450 retailers in the USA and Canada, they perform over 5,000 truck tunings each year. The company has also done tunings in other countries.
Tuning is the process of fine mapping the software of the ECM module, with the end result of creating more power, greater response and less fuel consumption. Diesel Spec offers 4 types of tunings:
•High Performance - for truck pulls and racing
•Performance - provides extra power for heavy loads and pulling mountains.
•Fuel Economy – that is self-explanatory
•Off-Highway - eliminates horsepower robbing add-ons
However, truck owners are urged to check their state laws before having an “off-road tuning” performed. The tuning itself can be done at any of Diesel Spec’s retailers in about 2 hours. The customer decides which type of tuning they would like performed, then a tuning module is plugged into the truck’s ECM and the tuning is performed remotely from Diesel Spec’s Montreal, Canada headquarters. Each tuning carries a 30-day satisfaction warranty and a one-year reflash in case the ECM is reset at a dealer. Both warranties are included in the price of the tuning.
Most customers experience a 5-20% (about ½ mile per gallon) gain in fuel economy. Tunings are available for nearly every engine type, including: CAT, Cummins, Detroit, Isuzu, Mercedes, PACCAR, and MaxxForce. Updates are also available for all modern engine versions. Diesel Spec also does tunings for farm tractors and off-road equipment.
Diesel Spec also sells high performance parts including turbos, exhaust manifolds, intake manifolds and crank dampers. The company has a Taylor dynamometer at their facility in Montreal to ensure more accurate results.

Tyler, truck owner from Alberta, Canada: “We did a tune on a Caterpillar bridge engine. Truck now pulls great and is good on fuel. CAT engine was lazy before. Thanks Guys!”
Doug, truck owner, Texas: “2007 Kenworth W900B with Caterpillar C-15 MXS twin turbo. I have the economy tune on my truck and right away you can see the difference.
