I have an 08 F150 XL 4.2l 4X2 with 265/70r/17 Goodyear AT/S running with a 3:31 gear ratio. Slow as hell and when towing 4 gear is a must lol

Those chips have been known to be really generous on mpg readouts lol

golferboomer

Well I go off how many miles I get to how many gallons I put in... Not off what the chip says

Call-_Me-Jordan

Ya I have seen some off by more than 2npg.

Did you recalibrate the speedometer to go with the bigger tires?

golferboomer

No not yet.... But if I put bigger tires ad getting miles per tank form the smaller tires... Wouldn't that mean I'm getting more?

golferboomer

Well I don't know if the place where I got the tires did but I will tonight with my chip
