MAF Screen
Removing the screen was a popular mod awhile back. I bought and installed a Granatelli intake system. From the front scoop to the throttle body. I called Granatelli about the MAF because it was screened. The explanation I was given is the screen helps stabilize the air flow as it crosses the hot wire of the MAF. I can't tell you if this is true or not.

The screen itself is not that restrictive. It's there to straighten out the airflow before it gets to the wires. A descreened maf on a stock engine would prob yeild .5hp and require a bit of tuning. Not really worth the headache. A stock Z60 maf would require less tuning but still needs to be done for minimal gain. You could go with a Speed Density Tune and get rid of the Maf altogether.

Plus:
You can tune within closer tolerances since you don't have the computer sorting between two sets of instructions.
You have an easier job tuning since you can concentrate on one table.
You don't have to worry about wierd MAF issues.
Minus:
Your tune better be right since you lose one of the checks and balances in the stock tuning.

The screen on the MAF smooths and straightens the flow of air coming into the sensor to minimize false airflow readings. On LS1 engines in vehicles with straight intakes like the C5 the screen isn't necessary. On trucks with the LS1 that have a side tube where the intake air comes at the MAF at an angle the screen is needed to smooth out the turbulance.
GM figured this out and removed the screen from the Z06 in '02.
My guess is there may be some cross model use of the same MAF sensor and therefore the screen is left in as a default.
Remove it or leave it, although if removing the screen is good for the Z06 it should be good for the other C5 siblings.

unless you're going to change your intake manafold and do some other extensive mods the answer to your question is the minimal gains you'll see are not worth the expense. Leave your screen right where it is.
