In Need of a stock MAF WITH Screen for my '01 TA

[NAVYGSE1]

Greetings everyone,
I am in need of a stock MAF for my LS1 TA. I ripped my screen out years ago and my newfound understanding from the "Tuning God's" has shown me the error of my ways.
I know someone must have one laying around in the community...please help me out!
Thanx in advance and keep up the excellent work here on the forum!

There are actually no issues with pulling the screen off if done right. There are people who will tell you different but there is actually nothing wrong with it if done right.

Pretty sure there's only one way to do it.... I wish I had the screen, been meaning to go to home depot to see if I can find some similar material to use, for a .5 horsepower loss I'd rather have it in there, Especially with the poor fitting slp lid...

By right I meant carefully so you don't mess the sensor up. Your not going to lose HP by removing the screen. It isn't harmful at all. You do know why it it is there right? It straightens out airflow but when you have a straight intake this is useless. Yes it changes the tables slightly but not enough to be harmful without a tune for a little while. You should get a tune but it's not going to hurt anything if you don't right away.

Thanx for the support! I know it shouldn;t make much of a difference, but then again I have read numerous different opinions on the screen and the stock MAF with the screen seems to be more accurrate and tons better than the Granitelli I have been running for 8yrs. I liked the kick in the pants the GMS gave me, but I am very anxious about getting the tune with the stock MAF. I will post what my results are after all is said and done!
Appreciate the feedback.

Just to be clear here -- modifying the MAF in any manner affects reported air flow. The MAF is a precisley calibrated measuring instrument. Incoming air travels over a wire that is heated to a set temperature. By measuring how much electricity is required to maintain the temperature of the wire, the MAF then reports actual airflow to the PCM in hertz.

Any alteration to the MAF - such as removing the screen, de-blading or porting it alters the actual versus calculated airflow. The result is that more air is entering the engine than is accounted for and this creates a lean condition. Although the O2 senders can sense the excess air and call for fuel to be added to compensate, the PCM does not run off the senders in open loop or at WOT.

Moral of the story: Leave the MAF alone unless you are tuning to compensate for the changes.

I agree, the lid is rather ill fitting, but I am glad to have it! I purchased my first lid from Quarter mile Performance and it fit like crap! Then I sent it back to him because he assured me he had a new design came out...never heard from him again! Then when I filed a complaint with the BBB, they said he had several buisinesses and they did not reply to their requests...so they closed the case and he walked off scott-free!
I just make sure my gasket is in place and carefully close it up...seems to work just fine for me.

Good info. Also as a further opinion, leave it alone unless you have over 500hp and need a new one. Stock one in original equipment and specs is juuuust fine.

Get a replacement Screen & press it into your existing MAF sensor.

re-read what I said. I was assuming the loss comes from putting another screen back in.
