Burgertuning also provided some info on engine tuning options for the X2 petrol, but I think their response is based on US market (228bhp engine):


"We have 2 tuners that will be compatible for you car.

We have the JB+, which will give you a quick 3-4psi with no hassle installation and you do not have to worry about settings.

We also have the JB4, which can give you power gains up to 40whp (50hp crack) on a completely stock car on pump gas.

The JB4 Features a plug and play installation and have features like 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, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more".
