#1 MAFs are awesome for tuning in general and they have the upside of adjusting for mechanical and environmental changes. Would you rather know how much actual air is going into the motor and add the fuel based on that or just know the pressure of it...
#2 I don't have DSMLink
#3 I probably will go speed density soon anyways.
I just feel like I have to defend MAF systems. People like to rush into overly complex setups too often.
