I am selling my Burger MotorSports JB+. This is a piggy back chip that takes just minutes to install.
This is off a 2010 335xi. It should work on any N54 Engine.
Connects directly to the map sensor on the Charge pipe.
Give around 30-40 WHP. Made a huge differnce on my 335i. The only reason i am selling is i have gone with a more serious tune after some recent modifcations.

The chip is adjustable from 50% being default to 100%. I have it currently set for 65% and i found it perfect.

Here is the link with more information on this product :

Burger sells this for 200 USD plus shipping.

Only been on my car a few months and it is in perfect shape.

Asking $170.

Thanks
