Is there anyway to calibrate this thing? Dads 07 cummins is rather generous in the reading.. It reads about 30% better than actual MPG.

Your absolutely right, thing will read 21, but actual is about 16.

My gasser is a bit less dramatic...shows 11, actual is 10.3.

I'd like to know the same thing. My '05 cummins reads 21.3, but doing the math by hand get me to about 16-17
