My '04 Tuono is bone stock, and am annoyed with the occassional "pause" or hesitation when at light throttle from 3400 - 3800 rpm. It is like the engine drops a cylinder for half a second. There is also surging at low rpm and light throttle openings. Popping and spitting on deceleration is noticeable, but I also noticed some exhaust gas stains between the collector and midpipe.
I presume a new EPROM would help driveability, but do not need the Factory Pro or anything else as advanced. Is there some other EPROM that will just help it run more smoothly, without surging and hesitation? Or is something like the FP chip my best bet? Not sure it makes any difference, but this a California bike and I probably will add a slip-on to the bike at a later date.
