The doubling of the gasket is probably more a contributor to the seat-of-the-pants improvement than any restriction you've added.
You've begun on your way to creating a 'high-rise' manifold, a long known performance enhancer.

Well, I already have a TB Spacer under the TB. I placed the screen under the TB spacer.

I am looking forward to seeing how this pans out as well as I am barely able to afford gas for this thing as it is.

Looking forward to your follow up.
That's a completely different thing. the screen will increase velocity for the franction of an inch of it's thickness but the air will slow down again as soon as it's past it. using epoxy in the manifold/runners is to eliminate dead space and therefore eddies in the air as it flows through. it keeps the velocity constant and reduces destructive turbulence

And then again, you would think that car companies would be shipping the European and Japanese more fuel efficient versions of the same US cars we have right now but they can't manage THAT either.

Interestingly enough, a college used this trick to convert a car to run on Ethanol, this, as well as a bit of heat made the ethanol atomize to combust even on the coldest of days. The only problem i see with this ( as well as on mechanical injection systems" is that an intake block, will make you have to open the throttle more to get the same power, but with out an o2 sensor (i have one hehe) it will not know that it is getting less air than it usually does at this throttle opening.... Rich booo.

So should I invest in one of the O2 sensor trickers?
