The turbo on the Cruze is making full boost (something insane, IIRC) right around 2000 RPM's after starting to spool at about 1800 RPM's. That's one of the reasons those cars MOVE when the go-pedal is hammered. The Eco really loves getting the snot revved out of it thanks to the long gears.

Making the turbo not spool on this car is very hard. And the car is a real slug off-boost since it's a 3200 lb car lugged around by a 1.4l engine. It's designed to have the boost to get any meaningful acceleration out of it. Just something that Cruze hypermilers will have to work around.
