No, he doesn't mention the M3/M4 (or when his long awaited video will be uploaded) but it is interesting to read his review and get the technical details of how Ferrari dealt with the 'problem' of replacing an NA engine with a Turbo engine.

In a nutshell, witchcraft, but it works.
(longer version: artificially limiting torque in lower gears so one is lulled into sensation that you need to rev it out to max to get all the power (even though power actually peaks below redline)).
I guess if the F80 were being sold for 3 times as much, BMW could have engineered seperately mapped torque curves for each gear like those Eye-Talians did.
