Turbo shut down in ecoboost

If you look at gmc and dodge they use active fuel management where they shut down 4 of 8 cylinders on v8 and 2 of 6 on v6 4 better fuel economy.I was wondering if that would work with the turbos. Where they would shut down when u don't need the power and when u need the extra power when towing, passing then the turbos would activate so when your crusing at high way speed they would be off 2 increase fuel economy.

Actually turbocharged vehicles with variable valve timing are usually more fuel efficient with the turbo boost when cruisng than without. They take advantage of having the intake valves open during a portion of the compression stroke. This is known as a modified atkinson cycle configuration. Leave the turbo on.
