Designed specifically
for the 2007+ BMW N54 twin turbo engine,
the Juice Box Performance Tuner provides
a safe and effective remap of the
factory ECU tuning. Since its release in
August of 2007 JB has quickly become the
gold standard for N54 tuning due to its
perfect blend of performance,
reliability, smooth power delivery, and
value. There are thousands of JB tunes in
use World Wide!
With the exception of gobs of extra power, factory drivability and refinement are preserved. The key is its unique passive design which allows the JB
to work in conjunction with the factory
ECU. Factory fuel economy is preserved when not racing, and the JB is one of the few N54 tuners that does not cause annoying check engine lights or limp mode conditions.
Installation takes minutes using basic hand tools and is completely plug and play with no cutting of wires.
The JB is not traceable through the factory ECU/DME
(Including the new 29.2 and later ECU
software and MSD81 ECU designed to
detect tuners) and can be quickly removed leaving no sign of modification. Installation is very discrete allowing most customers to leave the unit installed for basic service.
Most importantly, the JB delivers. This is how the car should have come from the factory. The additional horsepower and torque profoundly transforms the
BMW twin turbo from a mild sports sedan to a true sports car. Power is instant and pushes you deep in to your seat. Turbo whine at high rpm is slightly more pronounced making for a thrilling driving experience.
