I have been using JB3 for about 4 months now. Have done the other mods too, Evolution Racewerks diverter pipe with Tial BOV and dual meth bungs, Silver Bullet throttle body spacer, AMS race upsized intercooler, BMW down pipes and full performance exhaust, BMW race suspension, BMW upgraded brakes, performance steering, Cooling Mist meth kit and a few other cosmetic stuff like full carbon interior and exterior, Yokohama run flat tyres, adaptive headlights etc... To get back to the JB3...It is the best way to go! I did a dyno at AMG in Modderfontein and the car pushed 640NM and 287KW on the wheels, I am doing 0 to 100kph in 4.4 sec and the 400m sprint in 12 sec. I am now looking to do the turbo upgrade through Vivid racing and also the lighter flywheel. Talk to Chad Wentzel from SPORTECH in Modderfontein. He has direct contact with Terri Burger from Burger Motorsports who design and manufacture the JB. Service is great and any problems get sorted out very quickly. Depending on where you service your car you can eather leave just as is or set the JB to zero which puts it back to stock and leave it in. I don't have any problems.
