OK, I know that there is a huge debate over descreening the MAF or leaving it in place. Personally, I have my screen in place.
The major argument for removing the screen is that the Z06 was descreened at the factory because of the short stright flow that the air will take between the filter and the TB. There is no need to "straighten" this airflow since it is not running through a couple of bends in the intake. This is true, however, the computer was recalibrated to take this into account.
So ... for now ... I'm sticking with my screened MAF.
All C5 MAFs (except the 02 Z06) have screens in them to help in laminar airflow. The 02 LS6 MAF does not. GM realized that with the need for more air in the 02 Z06, they would actually take a harder look at the screen in the C5.
John Juriga (Chief Powertrain Engineer for GM) stated they use the same MAF as the truck, but that the trucks have more bends and turns in the intake tract thus requiring a screen to smooth the airflow over the MAF elements. From that research they discovered the screen was not really needed on the C5 since it has a relatively short tract to the MAF housing.
They programmed the PCM in the LS6 to accommodate this change.
