Juice Box Stage 3 Plug and Play

Stage 3 improvements include crank position for full 4D engine mapping, air intake temperature for on the fly thermal loading adjustments, direct solenoid control for precise spike free boost control, throttle input for factory like drivability, and fuel pressure control for diagnostic invisibility.

In addition new internal safeguards such as over-boost protection, boost spike protection, and maximum allowable boost solenoid offsets have been incorporated making the JB3 one of the safest tunes available.  

Because the JB3 was designed from the ground up specifically for the N54 platform, we were able to optimize the unit for reliability and ease of install.

The JB3 does not require complicated external power or ground taps which can leave tell tale signs of modification or trigger detection codes, making it the only true plug and play N54 system available. And the JB3 box and harness are designed to fit discretely in the  ECU compartment with no visible signs of modification.
