I am wondering if any of you have done anything to the car to improve mileage. Such as a reprogram, exhaust, filters, magnets around the fuel line.... Other then overinflating the tires close to 10 pounds over max (printed on tire 32PSI max I use 44PSI, with no problems at all) I have done nothing to my 2002 S-10 to achieve close to a record high MPG (for me) of 30MPG. The car was rated at 17-22 on the wiondow sticker and I now have 38K.
