Mileage

[MediumD]

I've seen two seperate STS's that run out of gas at about 1/8 tank. edit: everytime it's at 1/8 tank!

That sounds like a fuel level sender issue rather than a computer issue. Both my ETC and Mark's MPG are usually within 5% of what I calculate at the next fillup.

I have a hard time keeping my foot out of the gas so I only average 20-21 mpg. I know it is capeable of more if I just stop flooring it every chance i get.

And time to take pics too!

The tach is conveniently cut off in the picture... what RPM were you at? Also, does your engine normally run that low of a temperature, or were you doing 145mph cold?
