Horsepower and torque specs on ALL truck and car manufacturers engines are created from parameters which include blueprinted, seated engines and lab grade fuels. Horsepower loss through the drive train should be around twenty percent. Reams of paper have been exhausted on the neccesity of the Cummins engine in our trucks to be fully broken in before maximum horsepower and fuel economy can be realized. We're talking twenty thousand miles, here! You are not driving a short-lived flash in the pan muscle car, you own the best diesel pickup money can buy. It ain't about instant gratification, it's about long term love!
