Burger Motorsports JB+ piggyback tuner for MINI Cooper S with the N18 engine, which provides a plug-and-play performance upgrade by increasing boost pressure. It offers a noticeable power gain of up to 20 wheel horsepower (whp) and 30 wheel torque (wtq) by adding 1.5 to 5 psi of boost. Installation is quick and simple, and the device is easily reversible without leaving a trace, making it a popular option for a moderate and accessible power increase.
this is an awesome easy upgrade and it has an internal switch to raise boost 1-5psi. It simply installs on your mafs. It is one of the BEST bang for buck modifications.
i repaired and extended the wire harness , i DIDNT use solder i did it correctly. It doesn't effect it in any way other than making it easier to hide now if you'd like. The longer wire allows it to hide under the intake.
