Hey guys,

I just adjusted my Scangauge for the tires that I have on my truck. Before I was getting readings of around 16mpg in the city and 20+ on the highway. It was 19 for the tank. So, when I refilled the other day I also put that it was 2.7L and followed the manual for how to calculate how much is in the tank.

My tires now are 31.8" diameter and the stock ones are 28" ( I got this info from the web by typing in what tire size they were) So I did the calculation and got that I should adjust the speed setting by 12%, so I did. Now I am getting a reading of 26.5MPG mostly highway. I expect this to come down when I start driving around the city more as I usually do, but I wasn't expecting such a change (around 5 mpg gain at least). Did I mess something up??
