Anyone Found Trouble Descreening the MAF?

IMO, if your a DD or mostly driven on the street/highway.. I would leave the screens in place.. if your going for MAX HP at High RPM.. you might gain a few by de-screening.
At the Higher RPM range, the speed of the air flow would not be very accurate anyway at WOT. For low and mid range RPM, the screen does help keep the air flow straight and give the MAF Wire a better and accurate reading.

leave the front screnn in to straighten the air flow and to keep debris out and remove the end screen. seperate both ends, polish the insides of the housing. i did that to mine and notice a good throttle response.

I can say, that there's one thing I have learned about these cars. Messing with the MAF is gonna give you more headaches then you'll ever see in power returns.
Leave the thing alone, if you're at the point that you're making 800 rwhp and it's a restriction then you need to tune the car in SD/open loop and ditch the maf, o2 sensors and all that crap because at that power level they don't work right.
Leave the stock maf alone, don't waste your time with that 85mm slp one they are junk and fail more often then not, and all the other aftermarket supposed magic maf's are also a waste.
I've been 9.5 @ 142 mph, with a stock screened MAF on my car. I'm gonna be hard pressed to believe anyone that's gonna tell me that they don't work, and that it's a massive power robbing restriction. Put it this way, I'm pretty sure that if I change to something else, I don't in the most remote way expect the car to go from 9.5 @ 142 to 9.3 @ 145 or anything like that, hell I bet it wouldn't even pick up a tenth or a mph.

I have tested mine screened and de-screened. When you monitor the MAF frequency in the HP Tuner scanner, the frequency reading is erratic and bounces with the screen removed and is more stable with the screen installed at WOT. I did not see any performace gain either perceived or in actual lb/min of air flow improvement with the screen removed.
To say you actually have improved throttle response is hard to believe or explain but if the car was tuned after the install that could explain it.
