Actually he's an English Mastiff. His name is tank. He turned 2 on 1 June. On 3 June he was weighed at the Vet. His head wasn't on the scale but his body weight was....235lbs without the head.

So we're in Florida, made a 5.5 hrs trip to the beach. 93 octane with star tron fuel treatment , full load in the bed and my 240lb dog, wife ( no I'm not dumb enough to list her weight lol) daughter and myself (215lbs). Running an average of 65 to 90 the entire trip. 15.3 mpgs. Not to bad really. The performance tune I have from 5 star also.

I get 13.2. 37 inch tires same speeds.

So you think the 37s change it that much? Still isn't bad at all

How does one re-calibrate the speedo when adding larger diameter tires? Or does the ecm adjust for the change?

I live in a country setting speed limit 55. A mix of Highway 65 mph and country roads I just returned to the house 18.1 on dash. I always hand calculate at fill ups and find a 6 tenths difference less than truck shows. Yeah I drive like a little old lady easy on the pedal.
