Designed specifically for the 2006+ 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
the Juice Box BMW Performance Tuner 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 Juice Box 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 Juice Box 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.

  Stage 1 adds up to 30 horsepower, Stage 2 - JB Plus (JB+) - adds an adjustable 30-60 horsepower to the wheels, and Stage 3 adds up to 80 horsepower and 80 torque to the wheels (100hp / 100tq crank). For those looking for even more power we offer inexpensive upgrades to push power to the max. Our development 135i and 335i are the worlds quickest running documented 0-60 times of 3.5 seconds, 1/4 mile times of 11.8 and trap speeds of 120+mph!

To ensure your satisfaction all tuners include a 14 day money back guarantee. If you're not completely thrilled with the performance of your juiced BMW simply return it within 14 days for a full refund. We also offer an industry leading 100% trade up policy for customers who choose to upgrade to one of our more powerful tunes at a later time.
