[QUOTE="Yellow Horse, post: 10974693, member: 2027"] Dude, I told you according to my GPS my odometer is exactly what the GPS showed. I run the stock 3.55 gear on stock tires/wheels. I will have Van verify it but according to my GPS it is correct. I don't have a calculator handy but if it were programmed for a 3.31 gear it should have been off at least 5-6 mph. Not sure what the gas has to do with it unless ethanol increases mileage I htink is highly unlikely. Same as oil. 5W is about as thin as it gets. I run 93 octane. I do not use cruise control on hilly roads. I lift before I crest a hill and I coast most of the downhill side. I rarely pull any boost and try to pull vacuum as much as I can when I drive. [/QUOTE]
