MAKE YOUR RAM 2500 RESPOND FASTER

The RAM 2500 is known for brute strength and comfort that doesn’t quit. It’s made to haul heavy trailers, long work days at the jobsite, and still feel solid on the highway. But the drive-by-wire throttle system is restrictive and slows things down, especially when you’re loaded or pulling uphill. That’s where the FN Tuned throttle response controller changes the game.

The FN Tuned throttle response controller eliminates the throttle delay and lets you fine-tune how your truck reacts to your gas pedal input. Choose from four driving modes and dial in the right sensitivity across 36 levels. Installation is simple plug-and-play. Bluetooth control lets you adjust throttle response on the fly. Your RAM 2500 doesn’t need more power; it needs better response!
