MPG Clock Incorrect Reading

[J-Key]

My MPG clock is giving an incorrect reading along with the miles to go and outside temperature..

Any ideas? Im getting a re-map on the weekend do you guys think this will help?

they are not 100% accurate. mine alays tells me i can get 450 miles out a tank. i have yet to hit 350, nevermind 450.

it should be about 500% more than what its telling me lol
