I suffered from a similar issue a while back. Where the cut off seemed consistant to the RPM, but I noticed it was load dependant. The cut off point would be lower in a higher gear, amd the amount of throttle affected it also. For instance, at WOT in 2nd gear it may cut off at 6k rpm, and 3rd gear, it may cut out at 4.5k rpm, but at partial it may not cut out at all. Is yours like this also?
