Bmw m3 v8 engine usa vs europe spec.

Hi Guys,

I am new in this forum. I am an owner of BMW M3 e90 interlagos soon however i have got a problem...

Does someone know what is the difference between USA and EUROPE engine spec as the difference in fuel consumption is huge... I have got a USA spec car and my friend has got EU spec and the consumption difference is around 4-6 liters per 100 km.... As far as i know the EU is a bit more powerful so when it is more economical and quicker...why not to change the map...

Is it possible to change the map of the engine from USA to Europe without having any problems afterwards?

The difference in power rating is due to the different standards as euro rates
in DIN vs U.S.s SAE. As far as fuel use he drives less aggressive.
