Do not descreen your MAF, it will cause more harm than good.

On an automatic car, I have heard nothing but bad from descreening the MAF

PREDATOR-Z

Nope i dissagree, I'm descreened to shoot dry and no effect with tuning. But why descreen if not needed?
For dry N2O=>YES (you have to tune anyways)
For N/A, nope

is there any way i could replace the screen or would i have to buy a new one

PREDATOR-Z

it is not the screen but the porting with your mAF if you have any issues.

okay i just ordered a new that is descreaned it should be here soon. i have also heard that if yor descrean a maf on a automatic tranny that it sends codes to your tranny and screws with the line pressure to the tranny what do you think

Matt D

I descreen mine years ago with no issues, Don't think I gained anything either. But I did try ported end & it screwed everything up. You would think I learned my lesson, I just installed an ZO6 85mm maf with the table & now I need to do a complete retune (way rich 12.0)

this should be moved to external engine. mods please move!

PREDATOR-Z

You can use a ported MAF with a vacuum modulated A4 with no problems.
On stock pcm controled you'll have to apply some tuning

Don't descreen your MAF - you stand to lose more than gain. Lose streetability, smoothness and fuel consumption against a MAYBE of gaining 2HP. If you are that concerned about the MAF as a restriction or dry shooting, remove it and go MAFlessand put it back in after you have had your fun.

just leave it alone...you gain nothing...you will gain more by a 10 degree drop in weather than you will in descreening the maf...you only risk danger to the engine...is $4,000 worth 1hp

Martingale

I've heear from many people that porting is bad but decreening is okay. When I bought my car it had a descreened MAF and I bought a brand new factory one. The power you gain is so minimal I'd rather have an untouched MAF in my car. Plus, the screen is there for a reason...you don't want debris in your MAF. But if you must take it out I've heard it wont screw up the tranny, just don't port it.

yea but there should be no reason you "must take it out"

True, but there is no reason why we "must mod our cars" either LOL. More/faster air maybe? The filter (which I always leave in) blocks enough airflow as it is, why slow it down more with a screen?

its more trouble than its worth

The screen actually straightens out the air flow so the MAF can make more accurate measurements.

I suggest leaving it in.
