Instead of leaving your car in a lower gear, upping the revs, you will learn to shift early and open up throttle more. That's what every tutor will instruct you on any "efficient driving" course.
Like for instance the one of BMW I got a couple of months ago. When you understand frictional losses and rotational inertions, you'll understand why low rpms are key for efficiency.

1150 sounds a bit low. If you drop the RPM too much, the turbo is not able to produce boost. Most data I have seen from engine efficiency, indicates that it is highest around the torque peak at high load. With a driving style like yours, you risk soot buildup and a clogged particle filter in the long run.
