It won't be HIGH BOOST friendly. The design of the pistons keeps everything nice and cool to prevent predetonation.
Ford designed this motor with boost in mind, hence the forged crank and connection rods.

Idk why everyone is thinking the 2011 is going to be heavier.
The only thing changing is the transmissions which are maybe 10-30lbs at most more than the 5spd. And the 5.0 only weighs 10lbs more than the 3v.
