It has all to do with Full throttle height - and the way the power curves get due to it. P-40M very low will have an advantage, then its steeper power curve (higher FTH) crosses the P-40Es, and in medium height it is slower than the P-40E. But the P-40E maxes out at ~3000m, and then the power cirve goes backwards again, and crosses the P-40Ms curve again, so at alts of around 4k the P-40M should be faster again.

No, there definitely were some changes--the Hawk 81A is quite a bit faster in the 4.12 patch at 100m, and so is the P-40M, although I must have tossed the chart I did on it before the new patch came out. Fortunately, I kept my 'original' 4.11.1 version and reloaded the 4.12 version on a different drive from the original DVD and patched up from scratch, so I re-flew the 4.11.1 P-40M and re-recorded the intervals.

Attached is the chart I created just for you; there is very little, if any, change in the P-40E from 4.11.1, but the P-40M is a good deal faster, as one would expect from an upgraded engine and better (full wartime) production quality.
