I don't care what you say...

If you don't change your driving stlye, the power button does nothing...milage won't change. It's simply a different tranny program, that holds a gear till almost redline, when the throttle is held at 75% WOT or better...on a hill, again, with your foot in it a bit, it will kick down a gear a bit sooner. Since our thrashy ol Isuzu 6 runns out of breath long before redline, it really only helps to about 4500 rpm....the last couple thousand rpm is all clatter, and agricultural noise. My power button is always down, and I'm getting 18-20mpg combined. I rarely (almost never) go over 3/4 throttle.

I go full throttle just going down the street, and having the power button "on" kills my mileage on the highway. Especially on road trips, if my power button is "on" the power mode keeps my VX from shifting to Over Drive (4th) all the time, especially when using cruise control. Sometimes when I am in cruise control and the power button is "on" going around 70 or so, the VX stays in 3rd, but if I push the power button to "off" it immediately shifts into 4th (overdrive).

i WONT turn my power button on.... ive tried it before and it did not increase milage with my driving style...

also, i believe with our motors seeming to have a tendency to blow i dont think its good to rev them that high...
