I'm looking for one too. Just got and X7 30d and wouldn't mind a extra boost in performance.

Which tuner are u looking at that give u 195kw to 245kw?

I was thinking of using piggy back box first while car in warranty rather than remap esp for a brand new car. If something breaks, it usually happens in the first few years so warranty is important in my view.
