Airmassmeters are usually not used in racing since they are so easily fooled.

I wholeheartedly disagree. There are thousands of race cars which use MAF systems with success, IMO they are not nearly as sensitive as you suggest. Take a note of how many factory cars running boost use speed density systems and figure out why the other 99.9% of them instead choose MAF for air metering. Then notice how many cars retain these stock setups under race conditions and explain how they are so unreliable in both longetivity and sensing accuracy. All current production American setups use MAF, all Japanese boosted cars use MAF that I have seen, and there's very good reason for it.
