Unlock the full potential of your 2025+ Nissan Armada or Nissan Patrol 3.5L V6 twin turbo with the JB4 Performance Tuner from Nforcd. This intelligent plug-and-play piggyback works alongside the factory ECU to increase power and sharpen response, delivering gains of up to 75whp and 79wtq on a stock vehicle while maintaining factory-like drivability.
- Up to 75whp and 79wtq on a stock VR35DDTT 3.5 twin turbo engine
- True plug-and-play install connecting to two engine bay sensors to optimise boost, timing and fueling for quicker spool and reduced turbo lag
- Advanced CANbus OBDII integration for real-time tuning using pedal, throttle, timing, trims, AFR and knock data
- Preloaded with up to 8 maps for stock, 91/93 octane, E85 blends and unleaded race fuel, plus boost by gear for improved launches
- JB4 PRO Bluetooth included for wireless map changes, datalogging up to 40 parameters and free firmware updates via iOS or Android
- Factory-smooth drivability with compatibility across driving modes, read and clear fault codes, unchanged economy in normal use, fully removable and not VIN locked
Installation is discreet and easily reversible. Unlike a flash remap, the JB4 leaves the ECU untouched so the vehicle is never aware it is running higher boost. Housed in a rugged billet aluminium enclosure, the JB4 is designed and assembled in the USA and backed by a 5 year warranty.
