Its easy to match fuel on an electronic fuel injection engine, the hard parts is getting the air in. (mechanics.stackexchange.com)
Additionally, fuel injection engines generally don't use any fuel while engine braking. (en.wikipedia.org)
The result is a pair of lightweight direct fuel injection engines with class - leading efficiency, which provide significantly more usable low end torque and superior dynamic responses without compromising power at higher RPM. (sybarites.com)
