I have 265/65/17's. Mileage is nothing to brag about ~19 city/24-27 hwy. No air dam or block off plates.

Not immediately, recently my mileage has gone way up. I have a feeling I might have injector issues but I'm not 100% sure. My daily commute has changed recently aswell so I'm trying to rule out the larger tire size if I can.
