Turbo Gas Mileage Re: <VV>

[Frank DuVal]

No vacuum advance, but every other trick in the book for economy. 40 psi 
tires, electric fuel pump that shut off when the ignition was off ( I 
know, in theory this shouldn't matter), coasted down every available 
hill with key off, sslloowwww acceleration and quick to 4th gear, etc.

It still seems impossible, but the same host member  filled up the tank 
both times at the same station. Maybe it was a heat of the day phenomenon.
