MPG and Overdrive Question
OK I have a couple issues/questions here. My set-up is in my signature.
My truck is my daily driver and my drive to work is about 10 miles of non highway driving. I am running DP Tuner in 80 econ. Average speed may be around 40 mph. I am consistantly getting 11 mpg and that is calculated (not of the overhead computer). It was quite a bit better than that before I did the 4" lift and 35's. I have had the abs module calibrated for the 35's and the speedo is within 1 mph at 60 mph so I'm confident my odometer is accurate. Is this normal mileage with my set-up?
Also, at normal acceleration my truck doesn't go into overdrive until it reaches around 48 mph. I really don't remember but it seems like when I first got my DP Tuner that in 80 econ it went to overdrive around 40 mph. Obviously with my commute being mostly 40 mph or slower, I'm not getting into overdrive much leading me to beleive that this may be the culpret to my bad "in town" fuel economy.
