Yeah my average dropped thanks to reading here about engine load . I was accelerating really slowly with the ultra-light pedal touching, I thought I was getting best consumption, after reading here I kinda slammed the accelerator and changing at 2700 rpm and I couldnt believe my eyes when I saw lower averages.

I'll see how that goes.

Before I stumbled upon the information on this forum, I was using very light pedal with ~3000-3500 rpm changes, and now I'm using heavy pedal 2500-3000 rpm change and lower average consumption.

You'll want to keep an eye on fuel/hour gauges just to be sure you are in the right spot, but I think you will see best results between 3100 and 3900.

In my 2.3 Petrol Mercedes with an MPGuino, I always saw a dip in consumption at 1800rpm (every load/gear), which I presume meant that was it's BSFC sweet spot.
