Wide Open Throttle RPM DROP Problem: EVO 9 MR
I have had this known problem with my Evo 9 MR. Could it be a slipping clutch??? When ever I go WOT or near WOT at anything above 3000RPM, my revs hesitate and drop about 500RPM and then continue all the way to redline w/ no problem. For example I'll go WOT at about 4,000RPM and then the revs drop to 3,500 or 3,600RPM and then climbs towards redline with no further problems? Is this a slipping clutch or am I pulling timing? DOES ANYONE KNOW the answer to how to fix this well known issue? Please.. someone assist me.

I have a AMS ecu flash. It might be the clutch...?
