Dave,
I've always liked the tacho on the td5 to concentrate on keeping it at peak torque when offroad. Being my first diesel I had to learn that "sinking your foot in" wasn't the best option. (Yes, I managed to overheat the brakes (ETC) going up hill :angel:)
Being my first 2.25 D, I had anticipated that the tacho would help me understand the engine a little more. I take it, you just work on decibels.
