The point of the screen is not to keep stuff out of the motor, but to smooth and straighten the airflow through the MAF. This helps ensure that the air at least in part passes over the filaments. Some of the LS1 guys have done the descreening thing and really regretted how the car ran afterward. I left the screens (flow straighteners) on my LS1 MAF. At ~3.5 in diameter, I doubt the car would ahve ever run right at low load without the flow straightener.
if you want more flow, build a freq. to voltage converter and use an LS1 maf rather then that old bosch stuff. On top of that, used LS1 mafs are dirt cheap.

Personally, Id be more worried about the imposed 255 gram/sec airflow limit in the ecm rather then the airflow potential of the stock MAF. Doesnt matter much if the computer doesnt add fuel to all that extra airflow. With a small ammount of reasearch and tweaking to the stock calibration, a larger, higher flowing MAF that wont peg on decent motors could be used.

Its BS...the thirdgen screens dont straighten the airflow. They were designed to protect the delecate hot wire. In order to remove any airflow turbulance you would need fins inside the MAF. Remove the screens..they are a restriction...... Hey I got an idea lets all put the Tornado in our intake tubing.....if the screens straighten the airflow in the MAF so well imagine the HP gains of the Tornado.....Remove the screens..they are a restriction built into the MAF by the designers because they knew how delicate the hot wire MAF design was.

TPIS has an actual dyno sheet from where they removed the screens and fins from a MAF on motor with a cam. There is an increase in HP over all RPM ranges, with some gains as high as 10 HP.

I took mine off in my LT1, it was WAYYYYY more restricting than the TPI ones (i only had 1 screen btw) and I noticed that at WOT on the top end it breathed better.
