The PSI Power Performance Module is designed for 8.3L and 9.0L Cummins engines equipped with the CAPS fuel system; this plug-and-play module optimizes engine fueling to deliver up to 30% more horsepower and torque, along with claimed fuel savings of 10–20%. Whether you're driving a motorhome, hauling heavy loads, or tackling demanding grades, the added power and improved throttle response can make a noticeable difference in how your Cummins performs. A three-position switch lets you select the power level that best suits your driving conditions, giving you the flexibility to run stock power or step up performance when you need it.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional programmers that reflash the factory ECM, the PSI Power 12100 works inline with the factory engine signals to optimize fuel delivery without changing the ECM's stored programming. Its plug-and-play connections allow installation without cutting or splicing factory wiring, and the included three-position switch makes it easy to adjust power settings. The module offers stock, approximately 15%, and up to 30% increased power levels, with performance adjustments designed to improve both pulling capability and fuel efficiency.\u003c\/p\u003e","brand":"PSI Power","offers":[{"title":"Default Title","offer_id":67980450496877,"sku":"PSI-12100","price":795.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/12100-2.jpg?v=1794524221","url":"https:\/\/dieselpowerproducts.com\/products\/psi-power-performance-tuner-98-05-8-3l-9-0l-cummins-engine","provider":"Diesel Power Products","version":"1.0","type":"link"}
