JB4 Tuner for 2024+ Maserati Granturismo Trofeo & Modena

The JB4 is a plug and play tuner that attaches to two easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. Unlike other tuning systems for the Ghibli, it also includes a fully programmable CANbus system, upgradable firmware, and data logging capability.

The default map is 4psi over stock peak and maps can be changed using a BMS data cable or Bluetooth adapter.

Installation is very discrete and it quickly removes without a trace when needed.
