Weird transmission

JSinnard Interesting, your experience. On our SR5 V6 we got between 23.5 and 25 mpg until the flash. I admit I watched the mpg visual and was moderate in my habits. After the flash I get no more than 21.5 mpg.

 

How long since your reflash and how much of your driving mixed between city and highway driving? My 40 mile round trip daily commute averages 55-65mph depending on traffic and I don't use cruise. Traffic is too erratic to use it.

Round trip highway commute averages 23.5 mpg but the city trips knock it down to 20 mpg per tank overall.

I also have a roofrack, sliders, up sized tires and a toolbox in the bed with about 100 lbs of gear in it so I'd expect numbers just under advertised.
