Unlock serious, switchable performance from your 2021+ Ford Bronco Sport with the JB4 plug and play tuner, available from Nforcd. This discreet piggyback module connects to two easily accessed engine sensors and works alongside the factory ECU via CANbus to optimise boost, timing and fuelling. Expect gains of up to 60 hp and 80 wtq at the wheels on a stock vehicle, with crisper throttle response and reduced turbo lag, all without permanently flashing the ECU.
