Fuel Econ and Hiway Mode

[rr]

If I had a choice, I'd forego it. Take a look at the inside of an exhaust
pipe. Now think of what the egr is doing to the inside of the plenum,
runners and the throttle body.

Some engines have the egr dumping into the plenum right behind the
throttle body. What a mess it makes of things. IMHO.
