Lower fuel mileage

Fixable by going back to stock. You've modified intake & exhaust to suck more air & provided more fuel to avoid being too lean which equals lower gas mileage.

I recently tuned mine as well using the FP3. I've noticed that my fuel mileage has dropped as well but the bike runs amazing.
Like 66cruiser and 1Canuck stated, our bikes come from the factory tuned lean. So with the bike pulling more air through the air cleaner and pushing more exhaust, it requires a little more fuel to run in the stoic air/fuel ratio mixture range.

I have a 14 Fatboy Lo and have been running FP3 with super radius pipes and upgraded AC since June. I just settled in to running a consistent map that I like and did a semi accurate mpg run 'cause I thought I'd lost quite a few mpg as well. I was pleasantly surprised to be getting 40.8 with a whole lot of mph law breaking to boot! I live in the country so I don't do much town driving though, mainly hills and twisties. Bike runs great by the way.
