Nearly bone stock, as in stock ECM, stock A/C and Rineharts, I was getting about 42, but the bike was nearly unrideable here in the Texas heat because of the detonation. After a stage one and trying XEIDs and a PCIII with about 20 different maps, I have gotten as bad as 32 (XEIDs) and as high as 38. Working on a configuration with the stock A/C box with a K&N and a canned map for this configuration. Will know mileage next week after I fill up. I expect about 36 or so. I tend to shift around 3200-3400 when hitting the freeway and cruise around 2800+.
I know people post they are getting 50 but I have no idea how. My '77 Ironhead Sporty maybe got 50, but not an 850 pound Ultra...unless you lug the crap out of it maybe. Maybe the newer bike's gearing helps get better mileage, who knows.
