Description

PSI Power performance modules safely and efficiently increase your vehicle's power and improve fuel mileage in a warranty-friendly package. Unlike traditional tuners that plug into the OBD-II port, in-line power modules from PSI intercept and modify the factory ECM signal en route to the fueling systems without communicating with the factory ECM. This plug-and-play tuning leaves no 'footprint' in the ECM, ensuring your factory warranty remains intact if the module is removed before dealership service.
