PowerSpec 4.3

PowerSpec is an application designed for North American users to help manage diesel engine and aftertreatment systems. It requires Ultra Low Sulfur Diesel Fuel for engines with Diesel Particulate Filters to ensure optimal performance and warranty coverage.

The use of PowerSpec is supported in North America only. For engines equipped with a Diesel Particulate Filter, Ultra Low Sulfur Diesel Fuel is required. Failure to do so can permanently damage engine and aftertreatment systems within a short period of time. This damage could cause the engine to become inoperable and affect the warranty coverage on the engine.
