Best GM MAS set-up Options

[KOU In3]

I've done a lot of the reading but I'm curious of the opinions from those who have tuned with them. What do you think is the best GM MAF set-up. Basicly the options are those below:

3" drawthrough
3.5" drawthrough
3" blowthrough

Second question. To descreen or not? I would think there would be less restriction without the screens but I'm thinking the 'straighter' airflow might be better. I've read lots of opinions but no definative data there either. Anything out there from you guys that have been all over the yahoo groups?

By the way, as you might expect, this is a sheer performance question. Not interested in venting for it's own sake. I'm leaning towards a 3.5" descreened draw-through set-up at this point but could easily be swayed.

I may not be correct but, this is my theory...

3.5 draw through would be great,

I would think blowthrough would give a more accurate reading, because it is actually meetering the air right before it goes in to the engine... so anything that affects the air, such as pressure , temperature and so on would best read right befor it gets set on fire
if you want to blow through, it should depend on your intercooler piping,

for example I have 2.5 piping, so i'm using a 3 inch, the 3.5 would not gain anything because after the sensor it goes back to 2.5 piping.

If you have 3 inch use the 3.5
or do whatever you want, it will all work!

another twist to the plot is it is rumored that the 3.5 sensor is more accurate, and easier to tune, than the 3... I don't understand how this is possible but, it's a rumor I guess
