Adjusted the fueling for my bike today. Since my laptop runs on Windows 7 Professional, I used Windows Virtual PC to run Windows XP mode to run the diagnostic program. I got the cable, dongle, and USB software driver CD from SEMCO Designs. When I bought it last year it had the "Power Up" work done to it and the single exhaust conversion (FMF muffler). As far as I can tell the air box looks stock. When I initially checked the fueling, low-mid-high were all set at 100. Based on DynoBob's advice in the first post of this thread, I set low-mid-high to 102-108-120 and took it out for a short ride. Fueling feels so much smoother now when accelerating and minimal popping when decelerating. Bike has better acceleration up to freeway speeds now too, feels more like my former TR650 (which was running a custom tune using a Power Commander V).
