If you have a turbo charger on a diesel install a boost gauge. Driving in a manner that keeps boost low shows you are driving efficiently (DO NOT MODIFY YOUR CAR TO LOWER BOOST).

I have tried a lot to find a BSFC map but without any luck. I have found a dyno run though which shows the torque starts coming at about 1800 rpm and rises until it reaches peak torque at 2600. However, I would assume that peak torque comes with high boost. To complicate manners a bit, my car has an eco button that remaps the engine for higher efficiency by reducing throttle response and torque by 10%. Should I drive with the reduced torque map or is it more inefficient?
