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.

your smart nate...
I would not have realized the turbulence that would be associated with the blow through setup.

but would it really be any worse than the sensor in a drawthrough setup?
I figured that the air is going to be changed, when it passes through the intercooler and turbo, than when its sucked through the filter.

i guess either way works great, as long as it is installed properly
