MAF screen removal
So I did a search and found a "MAF screen removal thread" for early C5's but nothing on screen removal for an LS2. Is it easy? does it help? are there any gains to be made? Looks kinda restrictive to me. Thanks for any help on the subject. Is it safe to use MAF cleaners like pictured below.

If you're referring to the screen on a GM style MAF, I wouldn't remove it since it has something to do with straightening airflow. I did it in another car and regretted it--rough idle, CEL, etc.

Yes.
Yes, it can.
Yes, there can be some very minimal gains.
What others have stated above can be true.
I personally have had the MAF screen out of my LS1 Z28 for almost 9 years and it's been out of my Corvette LS2 for over 4 years. Both cars have been professionally dyno tuned of course.
ZERO problems with surging, idle or driveability in either car.

Oh it's out there...here's a big thread on the topic from a few months back:

From my research, most people who heavily mod say remove it. Those who typically do bolt-ons say leave it alone. It's probably a personal preference as I have heard that the LS2 MAF with screen can support ~525 rwhp. I removed mine because I damaged about 10% of the surface area during a previous install.
Some guys say you can see 3-5 rwhp, but it could be the accuracy of the dyno, different weather conditions (it's supposed to correct for this, but most likely isn't exact), and even the way the car is strapped down (reaching a bit on this). I didn't see anyhing notable by removing mine and I'm at 485 rwhp, FWIW.

That was my thread... I can say first hand that it doens't have any negative drawbacks. It probably isn't worth it unless you are at the limit of the LS2's air breathing ability. Also isn't worth unless you see a tune in your near future just in case you do run into problems - the tune can resolve any potential issues.

Well looking at the screen, it looks like it is somehow glued in at the edges. Is cutting it out the only way to get it out? Doesn't seem worth the risk if I cut it out, have surging issues as mentioned above and not be able to put the screen back in.

does this rip out the screen? or will it come out with a ring of some sort? I see three floating diodes too and what looks to be an IAT sensor. Would hate to damage those.

The screen does rip apart (in half actually) and it can't be reused. Try pushing very close to the center. The IAT sensors are sensitive so just be careful but it's very easy to do. I yanked the screen on both LS2 C6's as well as both of my LS1 Camaro's with zero issues. Be a man
Same here.

Yes leave the MAF screen attached. The engineers at GM are smarter than all of us combined on the Corvette Forum.

But, I shouldn't use drag radials because the stock runflats will actually hook better as, well, that's what the engineers spec'd for the car?
And if I'm road racing/cornering hard I shouldn't put in a more supportive (Sparco, Recaro, Arizen, Corbeau etc.) driver's seat to hold me in better because the engineers know better?
Funny, those very same engineers also left the MAF screen off of the 2002-2004 C5 Z06s....maybe they simply forgot to install them?

Doug, no disrespect but do you know any GM engineers? I went to college with a couple guys who ended up working for GM and they aren't always the cream of the crop. I'm not saying that GM (in general) doesn't know their stuff because they do - look at the product they gave us. I'm saying that sometimes hidden restraints such as emissions goals or budget limits will persuade the finished product.
Sometimes the guy who tinkers with stuff around the house taking things apart will ultimately understand more of the actual dynamics under the hood. I'm not the sharpest guy out there, but I can figure out just about anything given enough time. Not true for everyone, but please be careful when you downplay the ability of some members here. If you question the ability of some people, read posts by Spinmonster, Sparo, Subfloor, Mez to name a few. True poineers in the Corvette world in my opinion, extremely sharp guys. They have done things that others said can't be done.
BTW, the GM engineers I went to school with graduated with a 2.9 compared to my crappy 3.8...
I guess they really do know more... or do they?
Not trying to start a war, just understand that sometimes simple inginuity does more in the real world than a computer.

This post is a wealth of information for those who read it. Many people start new threads because they want help or opinions of others who have been through the same circumstances. Simply posting the same comment over and over again, especially when downplaying the intellignece or ability of several forum members, does not help the OP in his quest for an answer.
