30th anniversary

About Tuning
ECM tuning is the process of fine tuning the software program that controls your engine fuel management system, without having to replace any part. Optimal tuning reduces the engine maintenance costs and increases the life span of the engine, because a better combustion means a cleaner engine. With the fuel price increasing, fuel economy has become an essential factor for the survival of any trucking company. This is why our tuning service contributes to reducing your costs, while increasing your engine performance, and allowing you to save from 5 to 25% in fuel in each truck, or an estimate of half a mile per gallon, says Christian Fournier, Diesel Spec’s President.
A new location to better serve you
A brand new shop was recently built at the cost of 5 million dollars, and is equipped with two dynamometers, one for highway trucks, and one for farm equipment. Our team of 15 employees offers a flawless service, guarantying performance and fuel economy every time.
