Ag Diesel Solutions Performance Modules CAT4000 Details

Ag Diesel Solutions performance modules from PSI Power increase your vehicle's power safely and efficiently, giving you better fuel mileage in a vehicle warranty-friendly package. Rather than plug into the OBD-II port and communicate with the ECM like a traditional tuner, in-line power modules from Ag Diesel Solutions intercept the factory ECM signal en route to the fueling systems. The intercepted signal is then modified by the power module and continues on, providing all the benefits of efficiency and performance programming without ever communicating with the factory ECM. This plug-and-play tuning means there is no "footprint" in the ECM, and as long as you remove the module from your vehicle before taking it in to the dealership for warranty or service work, they will never know it was installed, keeping your valuable factory warranty intact.

The adjustable three position switch allows you to adjust on-the-fly from Stock, +15%, or +30% Horsepower. There is no ECM flash required. Instead the module receives the data from the ECM and optimizes the signal to the engine to improve both power and fuel efficiency. True Plug-and-Play connectivity means you won’t need to cut or splice any wires. Just connect the Heavy Duty Truck Edition module into your existing factory connectors.
