Having read lots of reviews of Power Commanders, I gave it a go. HM Racing in Edenbridge fitted a PC111 USB and did a custom map. They identified that the bike was running in a dangerously lean state and fitted a lambda sensor from a Ducati 848 prior to a second go at the map being installed.
Massive improvement. Although still prone to a bit of stalling when cold, the bike now runs much more smoothly and the stalling problem has been reduced by about 95%. I now have rides without a single stall. As a side benefit, the bike has gone from 110.27 hp to 117.82 hp at the rear wheel!. The torque has also gone from 71.91 ft-lbs to 82.83 ft-lbs.
HM were impressed with the bike generally, particularly the power and quality of kit as standard. The only negtative was that the airbox is apparently quite poorly shaped and could be altered to provide even more power, although in their view the bike doesn't need it. I think I agree, although it is still tempting.
HM's workshop is the the cleanest I have ever seen. Not a drop of oil or dirt anywhere, and several liveried full race bikes in situ being worked on. I would definitely recommend them.
The fuel economy seems about the same, at about 36-40 mpg, but I haven't had it back long enough to be certain yet. The power and torque improvements are noticeable.
As always, there is a down side. The PC, Lambda sensor and custom map cost me £600 inc VAT. but the improvement is worth it.
