I had a PC-III fitted to my new 2003 SV-1000N soon after I'd bought it in July, 2003 and fitted Yoshimura mufflers, a K&N air filter and Ivan's Smart TRE. The shop that fitted the PC left it as delivered and it ran much too rich. The PC (at least at that time) could be adjusted manually through a range of about 5 settings (from baseline) leaner or 5 settings richer for low, middle and high rpm. I finally set all three at the leanest of 5 settings, watching spark plug color, coolant temperature (188F) and mileage to give a seat of the pants idea how the engine was running.
After 10 years and 39K miles, I have left it alone, completely satisfied with how the SV runs. There are no flat spots in acceleration. The engine pulls cleanly from 2000 in lower gears in local traffic and never pops or spits on decel (I removed the PAIR valves and fitted a Chewy's conversion kit.)
Original spark plugs look fine at nearly 40K miles and mileage consistently is 45-47mpg, per checking at every fill-up. In deference to my advancing years, I ride rather sedately, but there are times when no one is around...
