My opinion is that on an L67 (ether Gen) it can benefit those with smaller pulleys IF you already have a good laminar-flowing intake, and your MAF sensor and PCM can compensate.

A intake and MAF screen is in front of the blower. A restriction there increases vacuum to the inlet. This in turn creates a larger pressure differential from blower inlet to blower outlet. It also reduces the amount of air that the blower can move because it’* sucking in a less dense charge.

My car idles like *** without the screen. Low end torque seems a little better screen less, but upper RPMs kinda fluctuate and lose a little power because the air loses laminarity causing bad MAF readings. I leave my screen in for better top-end and idle quality.

yes but an Innaccurate MAF reading will cause you problems
So you must of forgot the last part to that. . . .Taking out the MAF screen will not alway cause you to have innaccurate readings. Problems must have to do with poor intakes and/or slow/erratic sensors that can't learn. But I honnestly don't know why some of your cars are doing it? Every car I've done it on or heard that it was done has had no problems with it. That is with stock intakes and custom ones.

I took mine out of my LN3 and there was for a day a few engine "coughs" but it runs great now, I felt a difference small but take what you can get!
