702hp is good, but 850hp is better!  The Ram TRX is an amazing truck, but we always want more don’t we! This package uses the knowledge gained from modifying and tuning hellcats and applies it to these awesome trucks while maintaining engine and drivetrain longevity and safety.  Featuring:

-Additional 4-5 psi of boost through a smaller supercharger pulley and upgraded belt

-JMB 5″ cold air intake kit for much higher flow and great sound in your color of choice

-Larger Injector Dynamics fuel injectors to handle the increased power

-Colder NGK Iridium spark plugs for the added boost

-Unlocking of the ECM with access cable for flashing

-Custom tuning of the ECM while staying emissions compliant

-Custom tuning of the TCM for firmer and quicker shifts

All of this adds up to an additional 150hp, improved throttle response everywhere, and an amazing sound!
