My mpg on the dash, which for me idk if its because 3.73 is always dead nut with hand calculated was actually worse. But this may have been my driving style with the new tune and the area I was in. It was showing 17.6mpg and even after a short 10-15 mile interstate ride it never moved. I switched back to the old race friday night and after about 175 miles of the same roads as the new tune it steady rose to 19.7mpg now.

My dash is never accurate vs hand calc, having run stock, KEM and now IDP, none are correct.
If my dash says 21-23, I can get 18+ish w/ IDP by hand.
