What MPG are you getting after going F.I.

Turbo's help the motor exhale and breath. All else being equal, cruising MPG should go up. BUT, part throttle and WOT get so much worse that it more than makes up for the extra you get while cruising.

That is not true. Turbos are mounted on the exhaust. They create back pressure and restrict exhalation.

And turbos doesnt necessarily help the car inhale better either. At cruising speeds, the turbos are not spun fast enough to create boost. The engine is running in vacuum.
