Modifications affecting your gas mileage
Wednesday, September 13, 2006 8:06 PM
This is not for those with just intake and exhaust.

Those with most of the major bolt on including cams should answer.
City 16-18mpg
Highway 26mpg

3400 V6, with incorrect ECU, continuous open loop operation. Guesstimate 9-10mpg.

let's see.

with the mods listed in my reg.

City: 19-22mpg
Highway: 25-30mpg

Somewhere around there.

I can still make it home from san diego to Winnemucca nevada, in more or less the same amount of gas/fillups that I used to take. so as far as I know, I only lost a few mpg.

Turbo'd with a chunk of boost and a bigger chunk coming I see around 500 km/tank (around 300 miles) driving it somewhat nicely hitting some boost.

If I plant my foot..... well you can almost see the gauge going down.

Haha.
