More About Us

  • BR Powersource Ltd. was founded back in 1999.There was very little electronic automotive tuning available in Canada so most customers had to seek programming and or chips for their modified vehicles in the US. We recognized this void in the market and acted upon it. By the year 2000 we became a corporation and actively continued to train in this field as well as help some of our manufacturers produce many performance products suited for our Canadian environment. This was done through extensive testing and programming input.
  • Personalized performance tuning and or package matching for each customer's demands. All levels of performance upgrade packages for most late model GM, Ford and Dodge trucks and SUVs, for both diesel and gas engines. The same is available for most late model Ford and GM cars. Customers can tune their vehicles to accept bolt on modifications such as camshaft changes, gear or tire changes, raise or lower transmission shift points, speed limiters etc. These upgrades are available in forms of programming tuners, computer chips, exhaust systems, diagnostic scan tools, gauges, transmission upgrades, fuel injectors, cold air intake systems and more. Other than just performance most customers experience significant increase in fuel economy as well. Specializing in most GM vehicles 96 to current gas/diesel performance/mileage tuning.
