6 inch lift on 37s by da way
You would be VERY surprised at the power gains, and probably the fuel mileage gains with the 275 tune. If you can't justify the $300 cost for that 1 tune, get the 275 and 310 tunes for $400. That is much more justifyable. The torque converter lock up on those tunes makes them so much sweeter than the 250 tune IMO.
