First of all I'd like to say that I'm not a gear head what so ever so thanks for your patience.

How difficult will it be for a tuner to push the envelop and see the true potential of our engines by upgrading the turbos and tune.

I hear a lot about upgrading the tune but what about upgrading the turbos?

The E60 M5 has just developed a supercharger a few months ago. So it took over 5 years after the car was released before anyone made the upgrade.

Will it take that long on the F10 550 engines as well?

Thanks !
