BMW N54 JB4 Tuner with Device Connection and Dual Cone Intake Combo

This combo saves money in one easy-to-order package.  

The factory 135i, 335i, 535i, and Z4 35i ECU comes detuned from the factory and the full potential of the N54 twin turbo engine is inaccessible. That has all changed with the introduction of the BMS JB4 processor. The JB4 is the latest generation of the Juice Box Performance Tuner and it features completely new microcontroller based hardware, numerous input/output channels, and integrated safety features.
