provided by Terry Burger of Burger Motorsports. I decided to write this little post because I was impressed not by the product (I am though) but by the unbelievable customer service and email responses that I received from Terry. A total of 34 emails since my introduction to Juicebox.

Vishnu is another tuner for the N54 engine and I have heard good things about the product. So, I sent emails a total of 7 times to gather more information and have yet to receive a response. Now before I drop $1000 on a Vishnu tune (double the price of a JB) I would like to know if I had any problems I could send an email or call someone for customer support.


Below is a brief description of N54 tunes offered by Burger Motorsports.

JB Plus Quick Install---A true plug and play tune offering safe and adjustable 25-70whp gains. Can be installed and removed in minutes without any tools. At the default setting of +2.75psi average increases are 40hp and 50tq to the wheels. For those looking to take things to the max up to +4.75psi can be quickly dialed in! Does not trigger codes and does not require entering the ECU area for installation. Compatible with all ECU versions and transmissions for BMW 135, 335, 535, and X6.

Stage 3 Pin-out---Identical to Stage 3 Plug and Play only utilizing a pin out harness similar to Stage 1 and Stage 2. 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. Now shipping with software version 1.3, featuring in car map switching between stock and 8 unique performance maps and dramatically improved low rpm response and torque!

Stage 3 Plug and Play--- The latest generation of the Juice Box Performance Tuner features completely new microcontroller based hardware, numerous additional input/output channels, integrated safety features, a plug and play wiring harness, and gains of up to 80 horsepower and 80 torque to the wheels on an otherwise stock car! Compatible with all ECU versions. Now shipping with software version 1.3, featuring in car map switching between stock and 15 unique performance maps, including race gas maps, and dramatically improved low end response and torque!
