B47 - Mods & Software?

Hey guys,

So I am wondering whether anyone has done some mods (such as a downpipe) and software to a car with a B47 engine (2015+ F30) in it?

I know that only now we're approaching 5 years and I think that is when the motor plans runs outs, so doubt many would have been willing to do the mods sooner.

I am wondering what power figures and fuel consumption is like before and after the mods.
