What about fuel economy? Do you get any better mileage?

It definitely didn't hurt mine when I did the swap but as far as improvements it won't be enough to notice if it does

yes, you get 40mpg :lol:

it's probably all about how heavy is your right foot though regardless if it a stock t/b, a 4.0L or 62mm
I agree.  You're making more power, so it's possible the engine won't struggle as much & you will notice an improvement in mileage, IF you can keep your foot out of it.  Not easily done when the 2.5 becomes more fun to drive.
