Except it was on a Cobalt first, and that setup also manages boost not just revs.
"The SS has a feature called "no-lift shift," which means you can shift the five-speed manual gearbox without backing off on the gas pedal. You simply keep your right foot to the floor and bang off the shifts. A computer controls the revs when you hit the clutch.
All of the punch comes courtesy of the SS's 2-liter four-cylinder engine. Enhanced by a turbocharger, it pumps out 260 horsepower. Almost as importantly, it delivers 260 pounds-feet of torque, or twisting force, starting at just 2,000 revolutions per minute."
