I don't have any city driving. Mostly highway driving.
Last tank was only 22mpg but average driving speed was about 80mph.

Gas pedal and throttle both having low voltage at the same time sounds like an ECU problem. Good move avoiding that one.
The best it gets is about 26 to 27 if I slow down.

The whole electronic throttle on these engines is their weak point. If VW would have stuck with a normal throttle cable like almost everyone else was running at that time they would be about as perfect as an electronic fuel injected turbo motor could be.
