JD2453-PSI Power Performance Module for 4.5L John Deere Tier III Engines

Unlike traditional tuners, this module doesn’t flash the ECM. Instead, it enhances engine performance by optimizing signals sent from the ECM, resulting in improved fuel economy and power. Its plug-and-play design eliminates the need for cutting or modifying engine wiring, making installation quick and easy.

Engineered, tested, and built in the U.S.A., PSI Power Modules come with a 30-day money-back guarantee, a limited three-year warranty, and U.S.-based customer support. The increased efficiency ensures a fast return on investment.
