RE: Gas Mileage
I was getting low 40's (RH True Duals) before I put on the K&N 3910 and ThunderMax, now low 30's. Runs cooler and much faster.
Still tuning for cruising economy. I've adjusted the AFR to 14.4:1 in the cruise range. Then to moves to 12.5:1 on greater throttle. Have not ridden it yet with these settings.

RE: Gas Mileage
I'm getting 37-40 on a 08 with a stage 1. I didn't start checking it until after 5 or 6 thousand miles so I don't know where it was when it was stock. Mostly cause I don't care about the MPG. I only started checking it to get an idea how rich/lean it was running. Plugs look good, pipes look good. 37 MPG says it's a little rich somewhere but I'll track that down.

Ive got an 07 Road King and just had it dynoed. My gas mileage was never that great to begin with. Now I get 150-165 miles to the tank. Is that normal? What are you guys getting?

My mileage varies between 40 (city) and 50 (55-60mph steady).
