the maf that you use, has nothing to do with what fuel injectors "it will let you use", etc
stock injectors are 330cc
stock maf sends a reading for the stock injectors
ls400 maf sends signal 25% bigger (speaking abstractly here) than the sc300 maf
injectors that would be at stoich with the upgraded maf would be 25% larger: 412cc
so it gives you larger headroom to tune your fuel with vs the 330cc...
with the ls400 afm and 550cc injectors, you can tune it to where it runs correctly instead of super rich... normally wouldnt be able to do that with stock injectors since the adjustment you would need would be out of range for the S-AFC
make sense?

i suspect if it hits a limit; in typical toyota fashion it would cause some kind of fuel cut....
