ADDED NEXT DAY: I also asked for and received the following information on how to set the Highway side of the Enhancer: The Highway setting is for speeds above 40 mph. Match the HWY Dial to your City setting. After reaching a speed of 40 mph, switch to your dial to HWY and lean it out until your comfortable with your setting. Be careful and do this slowly. You don't want your engine to die at that speed. Also remember, when you want to pass or go up a steep incline, switch your lower switch to Factory so you will have all the power you need. Good info for all.
As I said in the last post I waited to fill up until I got the new gadget, so here are the results - as you can see I didn't do as badly as I'd expected since this works out to 22.9 MPG - (lets call it 23 why don't we) which is nearly couple of miles-per beyond my norm. This was obtained with the Oxygen Sensor Spacer installed as well as the HHO Generator. I suppose if I'd done the battery trick I would have done even better. It just occurred to me, (as I wrote that last line) that I didn't do it when I did the install - so I promise to go out and do it in a little while so that everything starts from an even base.
Wish me luck since my luck will also be yours...
