hauck fuel accelerator and gas mileage

[2008FxNytro]

Hey, i just recently added k and n filters, cr10 plugs, and a hauck fuel accelerator. just wondering if anyone has noticed a loss in gas mileage with the controller. went for a ride over the weekend and after lke 65 miles i only had 2 bars left. thinking about doing a few adjustments and run it again
