Re: LS Swap MPGs_What're you getting?

Thanks everyone for the input! Much appreciated. I think the 3.07 might be too short for my setup.

^^^ I'm going to reset the brain of my gauges and make sure everything is calibrated correctly, and rematch everything. Also the fuel sender was acting a bit funky so I'll look into that too. The idea that mpg is worse on the highway is absurd, I know! It doesn't make much sense at all, so I'll update again once I've got everything set right.

Thanks again guys!
