10-12 in the city or 15 highway driving like a dick

13 in the city or 15-17 driving like grandpa

I normally average about 12, but that's almost all city driving.

The speedometer on it is wacky though. I have 255/70r18 on it which are about 1.5" bigger, but according to the GPS on my phone the speedo reads about 3-4 mph faster at 75 mph.

Haven't posted in here in awhile. Have to say my mileage probably increased by 50% after i had the old, clogged cat taken off. Thing was robbing an IMMENSE amount of power, and killing the fuel mileage. Also, being able to race brand-new F-150's and obliterate them is a plus.

11.6 with 90% city driving on my last tank.

I've GPS's mine before- stock is 245, I run 285 but the speedometer is only off 1mph @ 60 if any

Does anyone know more about this? Do '98 Vortecs automatically calculate or something?
