I just used tuneECU to save the 2010 990R "stock" map my local dealer loaded onto my 990A ECU a couple of weeks ago. I sent it to Tom at tuneECU.com for them to post up.
So far, I'm happy with the tune. There is still some bucking at very small throttle openings, but I'm betting I can work with tuneecu and reduce the effects of this unwanted behavior. IMHO, the fueling on this bike is superb anywhere away from 0-5% throttle. I only wish I had a tire sponsor!!!
I just did a 500 mile jaunt and saw 38-40 mpg on a 155 and 110 mile legs, street only. I'm not trying to set any MPG records, I'm just looking for extra range when I decide to get out in the back country. I was not running the SAI and both O2 sensors online and operational. FWIW, I do not baby the bike and I do not ride slow.
