Speed Density or MAS

Speed Density or MAS
I am strongly leaning towards buying an AEM EMS because my mods are at the point where I think it will be better.
My question is what are the advantages of speed density over maf. I am going to use the stock intake, so if the maf restriction is the only advantage I will probably just use maf. How is the driveability witb speed density? Most everyone I have asked has said to use speed density, but I haven't gotten a reason why. Is speed density easier to tune? I plan on going to Dr. Gray for the tune, if that makes any difference.
My car is a daily driver, while I do want to make power, I also want to be able to go for a few hundred mile drive if I need to, and the car needs to be reliable. Thanks.

It depends how modified your car is. All mine needs is a large turbo kit. I went to MAP. The idle is better, driveabilty is way better and it doesn't buck at part thottle on the hwy. I drive my car every day it is not completely horrible out. id say it moves 325 days out of the year. It starts when its in the negatives in the morning every time. I had a little help with a starting point and I have hours of time tunning for every condition.

Thanks. I will go with speed density. My cars idles like $hit, and I would love for it to idle better, especially with the a/c on.

As for the idle, yes play around with your EMS more you will be able to improve that idle no matter what. I am looking at a standalone as my next mod. Like you said i want to see what my car can really do with these mods before moving on. Good luck and can't wait to see the results. Also can you provide a mod list i did not see any in your sig.

hey guys, about this speed density, im running the HKS Racing Suction Intake and come to find out, making it speed density will require me to have a custom fab. intake pipe in order to take out the stock MAF sensor and replace the MAP sensor....does anyone else have this same problem???
