mass air flow and speed density
im curious about what the difference is between the 2, which is better, how they work, etc. and i was also told that using a speed density computer on a mass airflow setup makes it run better as well. so ya just curious how things work exactly.

I'm not really sure how they work, but mass air is better I've heard. It can handle mod's that your gunna do and speed density can possibily hold a few minor ones and after that you need a mass air conversion kit.

RE: mass air flow and speed density
basically, speed density relies on a few sensors to estimate how much air is coming into the motor.
mass air uses a sensor in the inlet tube. this sensor has a wire in it which voltage is applied to. air rushing through the meter cools the wire and the computer senses this. with the help of a few other sensors it deicdes how much air is coming in and it can make accurate decisions on how much fuel to deliver,
razarr is right. you want mass air if you are doing mods that improve airflow in a major way such as heads, and cams.
