Not worth it IMO. Stock MAF is fine.

If you do a search we have had MANY pages of debate over this issue.
Are you forced induction?
90% of the time I've seen all that it does is richen the tune so YES if your lean and looking for the improper way to gain then try it.
But in my opion I'd never remove it. Buy an after market one that doesn't have one that has been calibrated like that if you think it's restricting your power.
Thats my 2 cents take or leave it.Don't be afraid of the bottle!!! Be afraid of your tune!!!

Yeah, leave it stock. If you want to do a MAF mod...go to Autozone, buy MAF cleaner, remove MAF, spray cleaner inside MAF, reinstall MAF, and enjoy.

No ill Effects
I damaged my screen trying to remove it for polishing the MAF. So.......it is now gone for good and have experienced no problems what so ever. I don't think its a particular big deal one way or the other. Some Venturi (want-a-be ) experts might take issue. I was more worried about something getting sucked in the engine....oh well.2000 Z28 M6, SLP Lid, SLP Bellows, SLP UD,

Boy were they confused in the late 70's to the late 80's. And the worst is alot of the books still sold were writing in that "cloudy" period. Don't get me wrong there is some old books that are VERY true. But there is also some were they just didn't understand the whole NEW aspect of computers anf fuel inj.

I agree with all above---leave the screen alone---I have EFILIVE Workshop (unlimited tunes) and when i went thru their training program--they told us that the stock screened MAF is good for 500 HP----A MAF in the newer LS engines that came screenless were callibrated for it being that way--I took the screen out of my '98 C5 to experiment and the LTFT's went nuts --over 25% at some points and it thru a code---It wouldn't shift properly either.I think you could callibrate one to make it work--but from what I've read there is only 3 HP there anyway--and it is not worth the days on logging and pasting work you would have to do to get that little of a gain.Having a data logger really dispells many of the myths about "free horsepower mods" as it shows exactly whats happening with airflow when you do someting

Don't do it. You might be fine doing it. But you will not gain anything so why fix it if it ain't broke?

Well, mine was already out when I got my car. I am getting it tuned very soon. Will it make it more difficult for them to tune my car? Will they be able to tune it?

The purpose of the screen is to smooth out the airflow. It should not effect it too much, when you port it it can cause some more difficult problems.
