Thanks for the answers.

 

Sure.

Aftermarket MAFs don't have a screen, so why should mine? Although the purpose of having the screen is to provide the heated elements of the MAF a laminar stream of air, I've never had a problem with varied MAF readings, and mine has been out for close to three years now. Other people might tell you differently, but in my instance, I say go for it.

 

id leave it alone...could cause probs. removing it...u wont gain anything from the removal anyway

 

Oh, I got rid of it 2 weeks ago, but I hear some people didn't like it, i was wondering what the problem was, in case it would be something I would run into.

 

I felt a slight change in the car after doing it. I did it after reading an LT1 tips article in a Chevy High Performance, and they dynoed an extra couple of hp out of it.

 

Symptoms can range from a number of things, including erratic idle, poor throttle response, etc., from what I understand.

 

You will notice there are two distinctly different schools of thought on this, Polar opposites actually.
Bottom line, if you don,t have any problems then leave it out.
FWIW mine has been gone for 5 years now.

 

Here's some more discussion on the subject.

Removing the screen "might" throw the calibration off. After market ones, without the screen, are calibrated for airflow without the screen. If your calibration is off, it might feel good initially until the computer, now getting an incorrect reading, adjusts the F/A ratio to something it actually shouldn't be. If ya take it off and it works for a while, great Otherwise put it back on i guess...

 

I figure it's there for a reason, so I've just left mine alone. It's sort of like the "coolant bypass" free mod. I figure GM has coolant going to the throttlebody for a reason.

 

The first thing you need to realize is much of the suggestions you read in car mags are BS.

I bought a used MAF and descreened it, ported it and even polished it. Kept my stocker.

Was told by Ed, when I had my PCM programmed for cam that I should put the stocker back on.

That was good enough for me.JMHO

 

As I understand it, it's a cold weather thing. I won't drive my 'birds on snowy or icy days, so... I'll probably do it

 

i descreened and ported my maf when i first got the car. It changed my BLM's and didn't add any noticeable gain. I now have a unmolested MAF in my car.

 

I've seen dyno tests that show the by-pass can give you a few ponies. Unless you live at the north pole, you shouldn't need coolant heating up your throttle body.

 

I finally found a printout of some dyno tests a guy had posted on the 'net several years ago. The site is gone now, but he used the dyno at Dynotech in Dallas to run a few of the popular LT1 mod's.
