Package deals are designed to get you a specific amount of added horsepower. For example, a Stage 3 Package can get you over 300 more horsepower and additional torque. Since horsepower is the product of torque, the more torque you have, the higher horsepower you receive. The package options from Custom Diesel features a backlit LCD display, high speed monitoring and data logging, and also reads and clears trouble codes. You can easily adjust parameters to increase performance.
