I don't think your problem is the brand of truck. I think it's your transmission choice.
An automatic trans is a marriage made in heaven for a turbodiesel because it shifts faster than a person can. This keeps the RPMs and the turbo spooled up and boost higher than shifting a manual trans. This makes the truck more efficient for racing.
Look at the tests Allison does against manual trans trucks. Even amateur drivers in an allison equipped truck can beat experienced drivers in an equal powered manual trans truck.
An allison equipped 250HP dumptruck can beat my 250 HP manual equipped dumptruck in a race.
