Why change? The maf measures airflow. Sd calculates it.
Stick with a maf. They are rescalable and the 482 and 399 maf are good for 300awkw+.
I cant think of a good reason to move away. I think that ecmlink has a good rep for sd. And evoscan/ecuflash is reasonable now but had issues earlier. Only other reason is if you have run out of loggable inputs, but there is a logging cable for ecuflash now that allows 5 extra inputs.
Space is only other reason
