Speed density or MAF

[DynoMaster]

I have read a lot about both but all the articles out there are just skipping so many things. Anyway can anyone explain the differences and uses along with how to use them in a simple clear way from the begining?

Thanks

This is a brief blurp about what they do.

If you are using a vehicle that will include both MAF and VE like it came from the factory (GM LS V8) on the tune you are doing it's going to be your best option. Having both dialied in with help the most with any type of driving, be it cruising around, freeway or the track. I'm likely bad at explaining things but the biggest thing is that you need the air flow into the engine mapped correctly to achive a good running motor.
