Designed specifically for customers who want to disable the factory speed limiter, improve throttle response sensitivity and those customers with aftermarket fuel systems such as a Fass Fuel System that require a specific calibration to enable compatibility.  

This calibration is designed for both L5P & L5D vehicles.

This PPEI calibration does not include any power enhancements or horsepower increase. Please reference the other L5P or L5D product that has a base price of $799 for the PPEI calibration that increased power and performance of the vehicle.
