How about up to 60hp to the wheels (80hp crank) on a completely stock car on pump gas for a B58 or up to 40hp to the wheels for a B48? The JB4 features a simple plug and play installation harness for easy installation and includes many features not found on any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built in data logging, built in code reading, and much more. It automatically detects between the B48 and B58 models at boot up making installation and setup a snap.
Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customisation but we strongly suggest the BMS DATA cable so you can load free software updates.
The Evolution Line exhaust system will propel the BMW M240i to the next step of performance tuning due to an increase in torque and power. Impeccably designed to fit perfectly within the lines of the car, this austenitic stainless steel system is finished with hand-crafted carbon-fibre tailpipes to increase the visual impact. It has a layout incorporating two central link pipes to replace the stock single version, designed for optimum flow of the exhaust gases. A dual-mode ECU-controlled valve manages the sound levels, which ultimately delivers a deep and fulfilling sporty note as the revs rise. EC-compliant and easy to install, the Evolution Line system is a perfect accompaniment to an already spectacular car.
