The volant is nice, I didnt notice much, then again at 4000ft i didnt really expect to. With the volant and corsa added I shaved about .15-.3 of my et if not more(base run 1/4 tank of gas- CAI,EX run full tank). The vera ram king cobra looks like it might be good. waiting hear more on it.

The screen is on the MAF to keep debrit from hitting the sensors. What could possibly be the advantage of removing it? And don't start with "it allows more air flow" Because the sensor is only going to allow a certain amount of air to pass.

Personally, I've done it on my brothers LT1 engine and it was removed by the previous owner on the T/A I just sold, but I don't feel the benefit is worth the potential lean condition and I don't intend to do it on my silverado ss.

Weeeell, yes and no
The MAF descreening can work and it can royally be a pain in the ***. It works when there the airflow is relatively straight and non-turbulent. For air streams that *are* turbulent or have a bunch of bends, descreening the MAF can become a programmatic nightmare for tuning.There is a limit on the amount of air a given MAF can meter, but descreening it won't reach that limit. A turbo on the other hand...
