You can actually see this by accessing the hidden menu and look at actual revs.

So the OP question is very pertinent. With an increased cut off to 8600RPM, does the needle on the tacho go past 8250 or does an indicated 8250 now correlate to an actual 8600RPM?
Really?So that means that my speed vs rpm calculations are off then!Interesting.
