Mileage on my second tank with EGR re-installed spiked way up, not sure if it's the warming weather or what, I've changed nothing.

w/ EGR 40.5, 42.2
no EGR 42.4, 43.1
w/ EGR 42.6, 44.9

But with the warmer weather, I filled with B50 and deleted the EGR again. I may alternate tanks enabled and disabled, just to see if a pattern will emerge. At this point there is no indication EGR delete improves efficiency in my TDI.
