EGT sounds a bit too low and running on the cold side. Verify the temps by checking the manifold with a heat gun. Manifold should be about 50 degrees cooler than actual EGT on its outside after the temp is stabilized.

Actual EGT only reaching about 650 - 700 degrees or so at high torque is a sign of excess cylinder metal temp absorption and flashing. Should be peaking 800 - 900 if sensor is inside the pipe. Have the SOI lowered about 2.5 degrees or so on it at higher torque and see if temps come back up. If so, then this was the problem.
