I thought you had a 3000cc engine. Must read further.

Let's just say I have 900 miles in front of me, and I'm taking back roads.

I want to do it with one tank, and beat a 3L/100km average (78 USMPG) for the trip.

I've had a 65 MPG tank which was 50% city and 50% highway at 53 MPH. This tank will be secondary roads only and I'll be driving 47 MPH, so I'm confident I can do it.

I did a lot of things since my last tank in preparation for this challenge:

Deleted passenger side mirror
Reworked my air dam
Added side skirts
Added full disk hubcaps
Deleted the radio antenna
Deleted DRL
Blocked the lower grills
Sealed front end gaps
Replaced dragging brakes and rear wheel bearings, packed with synth grease
Changed my MT fluid (200k miles on it) to Redline MTL
Logged a lot of data with vag-com to find best boost levels, timing and acceleration rates for my car (results were least amount of boost during cruise, max timing advance within specs during cruise, and the bsfc map was right about acceleration)

This will probably be as much, if not more, of a mental challenge than a FE one. It'll be 20 or so hours of driving at 47 MPH in four segments over two weekends.
