Smarty Performance / MM3 Tuning Overview

Smarty Performance King is a company that develops and manufactures electronic products for the automotive industry. They specialize in Dodge Cummins Diesels, and most Cummins owners utilize Smarty Tuners. Smarty stands for product quality, customer satisfaction, and customer service, creating complete, performance-oriented products that are simple to use. With a team of well-versed engineers and tuners, Smarty does the research and the production in-house without outsourcing any part of the process. Their experience stems from exposure to a professional racing environment, tuning high-end racing vehicles, and experience with software and hardware development. Smarty performance programmers feature "Torque Management" that distributes power throughout the entire RPM range. Smarty products' cornerstone is a software known as CaTCHER, which is included in their best products Smarty Touch and Smarty S-67.


MM3 is a sister company of Smarty King, that is specially devoted to supporting the MM3 Tuner.

The MM3 is based on the Smarty Touch hardware platform, but the MM3 is a custom tuning device without preloaded tunes. The MM3 allows Cummins owners to pick their own custom tunes and tune their trucks in whichever way they desire. Some of the MM3 features are data logging, reading and clearing diagnostic codes, and TPMS. We offer the MM3 with Custom GDP Tunes in one complete package!
