MAF removal?
Just wonder guys, I just installed a Halltech Stinger "SSM" air intake. I was wondering about the factory MAF sensor screen (honeycomb). Has anyone removed it? I removed mine from my 94 when I did a few breathing mods and the car seemed to be a tad more responsive. Any input is much appreciated.

This is an ongoing debate on the various LSX engine based boards, it's much like the ones about K&N air filters or synthetic oils...there may not actually be a correct answer but a search on the the topic of 'MAF screen removal' will yield you HOURS of entertaining reading LOL.

what'da think ??
imo, rotating the maf 90 degrees, to align the maf air diffusor with the throttle body butterfly is just as helpful as removing the screen.

Well I think after reading every C5 and C6 MAF post I will definitely LEAVE IT IN until I can find a good tuner in south Florida. HOWEVER I heard it cost about $250-300 for a tune, in that case maybe ill buy one of the after market MAFs that has a preprogrammed sensor attached for $350. Its all in one without the drive to the tuner shop.

you can change the flow characteristics simply by rotating the maf.
the butterfly opens horizontally.
the maf has an internal air diffusor (full length blade/wing . it is straight across the middle, connecting both sides, with an airplane wing profile) which directs air into the butterfly blade and hence forth into the intake manifold. As the butterfly opens, air enters into the intake through the openings. ram air is most effective when there is the least amount of resistance in the intake ducting (airflow).
by rotating the maf you are able to direct the airflow into the opening into the intake by use of the maf air diffusor. think of it as a ram effect adjustment. the better the ram air the better the flow.

thats what I learned and I will keep the stock MAF but I think ill try ZIGs rotation method to allow more air and not freak out the computer.

The CORRECT advice is - if you wish to remove the screen, DO IT, but
THEN have it tuned. Removing the screen changes the flow characteristics of the MAF- enough to screw up your fuel trims -warranting a tune.

Well, here we go. Advice is exactly that- advice. If you believe there's no advantage in removing a screen - as was done in the 02-04 Zo6 -
then of course YOU would advise leaving the MAF as is. OTOH, since there IS a nice HP gain (2-3Hp) in doing so, do it right, and
retune after the surgery.I'm advising from experience,not theory.
The last time I checked, this is the technical forum and populated with
a few adventurous types that want to explore the possibilities of
gaining a few ponies with approriate mods. It's called hotrodding?
The advice given is CORRECT based on the notion that my experience,as stated above, is both factual and helpful to the ORIGINAL poster's request for personal experience.

I supose if it were worth bokoo HP like say 15rwhp + it might be worth the aggravation. But it's not. I removed my 85 vette screen, my 3 Z28 camaro's screens and 2002 C5 screen, and I don't think it changed a thing. I couldn't feel it anyway, and the dyno proved that. These C6's are even more sensitive and will cause you some problems. I'm 461rwhp and my screen is in place. It's not hurting me.
