Many of the diesel performance companies are offering control boxes that can greatly improve power and torque numbers. One of the benefits of these systems in a diesel is that more fuel can be utilized whereas in a gas engine there is a point of diminishing returns if too much fuel is applied and the truck is running very rich. In a diesel, that fuel can increase the power much more efficiently though this doesn't mean that a hopped-up diesel is going to still run its stock mileage numbers when run at the highest setting. As with everything there is a price for performance, but in today's truck market diesels are the powerhouse players.
