Direct injection on turbo motors sprays metered fuel instantaneously in the combustion chamber to bring charge temperature down. That is why these motors can run high compression and turbo at the same time. Without it, it wouldn't work. That is my guess.

It sounds like the M3 didn't overheat which is interesting since that is a high reving, high compression motor.

Not saying anything either way, but direct injection is amazing stuff.
