I would bet there has not been a large change in the P-40s FM.
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.
