This is what i said. Could be one reason why a tuner gives you better mileage numbers. Another reason for me to buy one.

Oh well. I probably won't invest any extra money into finding out. I'll just go by what I know works for my other truck. There can't be too much difference in what speed it locks in OD.

She probably adjusts her speed a lot. I think my wife does this. Even though I drive a lot harder than her. I have an almost bald right rear tire to prove it. lol

Oh sorry. I thought you meant you'd like a tune where the convertor slips until a higher speed is reached.

When she drives the truck for a week, she'll use 1/2 a tank and only drive 100miles at best. On the other hand I avg about 365-375 in between fillups. And I too accelerate harder than does she.

Tell you this too. My daughter is 19now and I did not teach her to drive the way she does. Good grief! She's litterally GO / STOP There is no in between with her. Scares me to be a passanger... and her mechanic.
