That had an accelerator switch for cruising over 50 mph. When I did which was alot (and at very fast speeds), I would hit the switch and suddenly I had a sportscar. It was like night and day. If I didnt hit the switch I could tell the difference almost immediately. Got great gas mileage when I used it. Driving at speeds under 50 my gas mileage was not too good. I know what you mean. Now I have a sportscar and it just does it automatically and quite frankly gets better gas mileage over 80 er 75 er yeah 65 mph thats it. City driving in Baltimore really takes it toll on my car now. Glad you tried the switch! Hope that you will begin to see bigger differences with gas milage.
