Aircraft Performance with no CEM

[imaca]

I guess I am in a minority here as a non-CEM user. It seems to me performance of all aircraft has been greatly reduced when using simple engine management. So much so that it is virtually unplayable. For example, had a quick mission flying F4U vs Zero, AI zeros seemed to be faster. I would choose a 4.10 wildcat over a 4.11 F4U. Is this a problem that will be fixed or should non-CEM users consider 4.10 the last viable version?
