Thank you gentlemen, thine shall be done, hope i pick up .5 HP too

Bad idea, your mass air flow sensor (MAF) is a thermistor. That means the resistance of the wire changes based on temperature. The way your MAF works is it maintains a steady temperature and then watches how much voltage it must provide to maintain a steady temperature. As air flows across it the air absorbs some of the energy from heat of the wire thus cooling the wire off. The MAF then must apply more voltage the more air that flows accross it. In removing the screen from the MAF you are introducing turbulance (and if i remember correctly the air should try to flow towards the front of the pipe more) thus the MAF isn't seeing all of the air you take into the engine. The screen smooths out the turbulence and gives an even distribution of air accross the MAF sensor. There are no gains to be had in removing the screen. It is not a restriction at power levels up to 500hp. If you want to remove your MAF screen then remove the MAF entirely and get it tuned out.

MAF's can be tuned out.... hrmm i wonder if that would be better than getting one of the aftermarket ones like a grannetelli (sp?)

LiENUS

10000x better than getting an aftermarket one. the only thing is youl'l need to either gut your MAF entirely and disconnect the pigtail, find a pipe to go in place of the MAF or switch to a 93 style intake to do it.

z28hustle

well i actually have a 93 intake on the way so sounds good.

If your car is ODB1 and you are in Louisiana I'd be happy to tune it out for you. If you arent in Louisiana but have a cable and no tuning software. You can send me your current tune and Il'l tune it out for you as well... All free of charge. I do recommend going with pcm4less or one of those other mail order tune places though if you can afford it as I am not a tuner I merely have the software and hardware.

Well, it seems to run fine so far, no popping but it still has not gotten hot yet, i will see about eliminating mine too, i have a G2 cold air on the way, so i will be giving pcm4less a call in the near future, i was gonna eliminate the EGR and o2s prolly.

LiENUS

Tell them about your de-screened MAF bad choice de-screening it though, pcm4less will tell you themselves.

Hmmm...well, i will ask around some more, i was gonna port the stock MAF body tho, i dont know if i will be able to re-install the screen or not.

LiENUS

email pcm4less and ask them which they recommend.

Allright, just got off the phone with Brian @ PCM for less, he said it is a goos idea to remove it, so i will leave it that way, thanx.

ZONES89RS

Also, he said NOT to port the stock MAF, it would muck the caliberation.

LiENUS

Brian at pcm 4 less said leave the screen off?

ZONES89RS

iTrader: (25)

Yep, sho did, 724-349-4431, give him a call...

LiENUS

Then maybe they've figured out how to tune for it not being there, either that or they're just tuning out the MAF last I heard both him and the other tuner were recommending not touching the stock MAF.

Well, on a back to back dyno run, changing from a descreened maf to a screened one, my car gained one pony with the screen. Also, on the dyno pull without the screen my A/F was wacky and the curves were a little jumpy. That was actually the thing that we were trying to figure out and tried a maf with a screen and it brought the A/F back to normal and smoothed out the curves. I never noticed any problems with it in my daily driving travels but, watching it perform back to back like that changed my mind and I have a screened one now.
