Thanks to you, Ed, and the other fellows here for the information on the TCH. My car should be arriving by mid July. I have used the scan gauge with my last two cars. One was a 4-cyl, '03 Corolla and the other a '06 Ford Five Hundred V6. Strange, but both got peak mileage at 48 - 50 mph. The mpg would slowly fall off above 55 mph and even more at 60. I run 35 psi in my tires when cool. With the TCH I may go near maximum psi. I read that many run the max pressure here in the greenhybrid forms.

I wish I had bought the TCH when they came out. I could have had a years experience behind the wheel.
