MPG's on canned tune?

[BigRed4x4]

I've been running a custom 89 tune for a few years, since I bought the i2. I never ran the eco or gas saving tunes. I average around 17mpg's on the clock. What could I expect if I switch to one of the canned tunes for a road trip I am about to take?

Thanks

I have the 5 speed tranny (2010) and 37’s. I get 15mpg on the highway with the tuner set to eco and tire size corrected.

I'm running a BullyDog "Regular" canned tune with 89 octane gas. 2012 6-speed and I get 17 around town.

I run the canned Diablo 91 tune in my '13 with 6 speed/3.55. I average approximately 18-19mpg but my drive doesn't see much time in town. I've tried both the 87 and mileage tune and found both to get worse economy than the 91 tune.

Forgot to mention, HP wise, i tried the 93 canned tune, and didnt feel a damn difference HP wise. I will eventually get a jay greene tune.
