Genuine Ford Performance M-9603-B23 Bronco 2.3L EcoBoost Performance Calibration with the ProCal 4 delivery tool. More than one available, all new and never connected to a vehicle.
One box was opened only to photograph it, and its outer box has a torn corner (see photos); its label is dated 02/06/2024. The others are sealed (the photographed ones are labeled 01/14/2025, last photo). You will receive one of them.
Ford lists it for the 2021-2024 Ford Bronco 2.3L EcoBoost: 330 hp at 5,500 rpm and 385 lb-ft at 3,500 rpm, fifty-state street legal (CARB EO D-431-6 for 2021-2024 per Ford; the sticker in the opened box reads EO# D-431-4). Ford MSRP $850.
Important: Ford VIN-locks the calibration and the ProCal 4 tool to the first vehicle it is installed on, so it is not transferable after install. Because of that, it can only be returned if it has never been connected to a vehicle.
Premium fuel required for maximum performance (Ford). The ProCal 4 software needs a Windows PC.
