I cleaned the MAF with CRC electrical contact cleaner which is the same formulation as CRC's MAF cleaner. Results were negative. I then tried cleaning it with alcohol on a swab and got modest to no improvement. I replaced the MAF with a new Bosch unit and car is fixed! I'm measuring about 550kg/hr at 4000 RPM, 3rd gear WOT. This is what it should be.

btw, I've "fixed" a few Toyotas throwing lean codes by spraying the MAF but doesn't seem to work as well with these MB Bosch film type MAFs, at least in my limited sample group.
