Help Descreening MAF?!?!
So if the screen is important why did gm start leaving it off of the Z06 corvettes starting in 02? Also your car is going to pull air in to the motor in a straight line anyway, it would be necessary if it were going through a bend such as in the GTO air induction system where it comes in from the side of the car then makes a 90degree turn to the motor. Personally, i removed mine. Ill also add that i didnt really feel any difference before or after, also i took my maf apart to remove it, made it much easier to do, but as everyone above has said, once you take it out its trash and will never work again.
Mine was giving me hell... Put a screened one back on and walaa... cleaned its self up... Just my personal expeirience though...others may have better luck..

Wow... I thought you would be smarter than that... LMAO!!!!
The bellow is behind the Maf.. the meters are in the Maf where it gets read. The screen straightens it out.. The other Maf's you mention are calibrated without the screen.. Do you think GM put them in for fun
? Look at that picture you posted see where the bellow is ? Geezzz... Besides this was a good free mod for LT1's not LS1's
To the Original poster... Ask your tuner or a shop around you.. I had lots of issues when it came time to tune my car...

The mod works GREAT for any damn car out there, airflow restriction does not help by any means. Hell lets throw an EGR back on the these cars, and how about a air silencer...right?
The guy has a A4, he might need a little more fuel added...maybe. Us M6 guys get away with murder. lol
Peace,

It may make it run leaner. Simply put, i hope, your adding more air through the MAF, which reads and then should adjust the fuel accordingly. However your MAF may not like all that extra air coming in as the PCM is set to read the tables that were for the MAF with screen. Which is why some PCM do just fine descreening and others needs a little help. Its one of those hit or miss mods. I know i will be doing to mine but iv got tons of bolts on and getting a dyno tune and running a dry shot. With dry shot i dont want the screen hindering the nitrous flow through the MAF to read.
Why not take the maf apart at the four screws and then push the screen out. That is what I did and then you do not have to worry about the damage to the resistors/heaters. Just match mark the pieces and it will go back together easily
