you have a tune, so dont do it... messes up you a/f ratio. And the screen helps steady the air for the meter to read... IMO and per allen, leave that stocker alone, and dont waist money on an after market MAF. they dont increase power, just make the readings bounce arround.
you could switch to an i think its 85mm from a escalade.. but yea.. dont de-screen your stocker..
Yep, unless your MAF is a physical restriction in the intake tube (I've heard they don't become a restriction until the 600+ hp area) there is no reason to change it or mess with it at all.
Dont do it
:LOL: I thought so, but I didnt wanna be the first to say it.
U sure? My buddy bout a 85mm Granatelli and it was bigger than the stocker.
He said it helped him. He gotta 80mm BBK too so
wasn't my money. i'm not worried about it
All the MAF does is tell you how much air goes into the engine, and what temperature it is. Replacing it with an aftermarket one makes as much sense as replacing your coolant temp sensor with a "high performance" one. The MAF doesn't make power...it just feeds data to the PCM. Aftermarket MAF sensors are a complete waste of money.
well i gotta get a new one cuz before i found this site i punched the screen outta mine cuz i was listenin to people who said it would help. :doofus:
I've picked up a couple of used ones in the classifieds over on pt.net for around $30....not sure if they pop up on this site or not, but if you keep your eyes out you'll score one for cheap.
I had mine for sell here but it sold allready... check ebay, and post a wanted thread here.
Buying an aftermarket mass air meter that is larger in diameter than the stock meter is a mechanical advantage in that the larger diameter will allow more air to flow into the intake as compared to the smaller diameter unit. The gains are more apparent on force-inducted engines.
The purpose of the screen on the stock mass air meter is to "straighten" the air flow before it hits the sensor. This is to ensure that the mass air meter is acquiring accurate airflow information. I've read dyno tests that have shown a slight power reduction with this screen removed.

True to a point...a larger diameter MAF has the capacity to flow more air. The problem is that by the time you've reached the level of power that makes the stock MAF a restriction, you've already maxed out the hard-coded limits of airflow in the PCM. You could put a larger MAF in there, but you're still bound by the 512 g/s airflow limit in the PCM, so it wouldn't make any difference. At that point, it would be best to ditch the MAF completely and tune via SD instead.Quote:

yeah... its funny though cause every once in a while people cruise through and ask this and its like putting salt on a gunshot wound!!! :lol: I like watching the fun.
SD?
What's SD?

ok, it's clear now.
