The Dr. Performance Performance Module is a result of over 12 years of diesel technology designed to benefit you. This Module truly gives you the pulling performance of your RV or Big Rig.

The Dr. Performance Performance Module is scientifically proven to increase the performance of diesel engines like no other performance product. By optimizing the fuel plume of the air/fuel mixture while altering your engine's factory timing duration, microscopic fuel particles are mixed with higher levels of oxygen, causing greater volumes of energy to be released during combustion.

The bottom line is a cooler running engine with increased performance and improved fuel economy.
