JB4 Tuner — Ford F-150 Raptor R & Mustang Shelby GT500 (5.2L Supercharged)
The most advanced plug-and-play tuning system for your supercharged 5.2L Predator — up to 122 wheel horsepower on a completely stock vehicle, with no flash, no unlock, and no risk to your factory safety systems.
✅ Vehicle Fitment:
- 2023+ Ford F-150 Raptor R 5.2L Supercharged
- 2020-2022 Ford Mustang Shelby GT500 5.2L Supercharged
Real Power, No Flash Required
The JB4 attaches to two easy-access sensors in the engine bay and works with your factory ECU to remap boost, timing, and fueling for optimal performance and increased engine response. Because the vehicle never knows it's making more than stock, the install stays completely discrete — and fully removable, unlike a flash remap.
Fuel economy during normal driving is unchanged, and it's compatible with every drive mode including towing.
