Improving MPG

I understand the gauge is not always accurate Ferm but 205* IS the target operating temp on the LLY and LBZ to my knowledge and that's what both of mine have generally run. And yeah, I know the 160 bottom trick was a scam on the gauge. When you live in my type of climate it doesn't take long to realize it's far lower than 160* at idle in -10* or so weather.

I only have the info on the LB7, but I've seen a few logs from some newer trucks and they all seemed to run around the same temp. I have watched it on the V2 a few times now where the guage shows 205, but the V2 will only show 180 on other trucks both gas and diesel. So I never trust the guage, only V2 readings.
