i installed the economy tune about two weeks ago since gas is up to $3 a gallon again, I figured I'd go for mileage for awhile....HA, thats B.S. I actually lost over 1 mpg, maybe cause I gotta floor it now to get anywhere. I'm going back to the 87 performance tune today.
OK, I put in the 87 tune this morning, noticed a little difference in the shifting patteren, I will know a little more on the milage by the end of the week.
