Ready to take your BMW twin turbo to the next level?

How about up to 180hp and 155tq to the wheels on a fully modified car on race gas?

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 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.


Identical to Stage 3 Plug and Play only utilizing a pin out style harness which takes about 20-30 min longer to install and remove. Suggested for more experienced enthusiasts. No cutting required and easy to remove. Can be updated to the Plug and Play harness at a later time by purchasing the PnP upgrade.
