BMW Burger tuning N55 JB4 (Stage 2) - Harness Type A
$529 retail.

Includes the USB Cable on a 2011 335i M-Sport
Purchased in early 2012, Used for 8 months, upgraded firmware in July 2012

How about up to 60hp to the wheels (80hp crank) on a completely stock car or up to 100hp to the wheels (120hp crank) on a fully modified car? The JB4 features a simple plug and play installation harness and built in deletion of hidden "tuner detection" codes. Compatible with all ECU versions. With over 10,000 in use and tens of millions of customer miles driven the JB has proven time and time again to be the safest and easiest way to extract the true potential from your BMW turbo!

In perfect functioning condition & Easy to install

I also have an N55 BMW Downpipe for sale $200

Selling because I've sold the N55.
