Chipped mileage?

What kind of tires? I've found that tires make a huge difference- I lost a
good 2-3 mpg when going from 225 to 255 section tires.

Even with 255s running about 36 psi, cruising at about 85-90, I got 25-26mpg
on a 5 hr. trip. Chipped 200q20v with Lehmann software and Stromung exhaust.
