He thinks the tune needs to be adjusted based on what climate he's in. Someone put him under the impression that SD can't calculate for that...
But to answer the original question, the restriction is not in the MAF itself, it is in the limits of your computer...

SPeed Density may have been rough years ago to climate changes but in recent years the tuning abilities have made it a very good tuning alternative where MAF tuning is nonsufficient

My car still uses stock computer and a stock MAF!
Drive's good and wouldn't have it any other way.
I'm also on the stock MAF and stock computer...

I'm not saying tuning can't be done at all once the MAF is maxed out, it certainly can. I too am still on the stock MAF and PCM. However, it is maxed out at like 4500RPM and after that, the fuel that is added into the tune is based solely on RPM- it doesn't have a clue as to how much air is exactly entering the engine after the MAF is maxed out. It can be done, but it is a bandaid approach.

I agree that it's an unsafe approach. Fueling based on maxed out sensors (where there is no fuel compensation for actual measured airflow) is rather crude.
who did your tune? and what maf sensor you running? stock or like new zo6 or what?
