Default Gutting a 91-93 air intake

Ok sleeper_inc did a post on how to gut an early 2.3 fox air silencer. I have done the same thing, but I only removed the smallest part of the silencer, as I noticed that removing the larger part caused the engine to lose throttle response, rather than gaining it.
This is it:

And here is the stupidity of it:

of course you notice that the air has to go through a tiny little hole. my plan was to make this hole a little bigger.
So I pulled out the smaller part of the silencer:

BTW I just stuck a lead pipe into the silencer and pushed the smaller piece right out.
I had to adjust my idle a little, because it dropped to about 850 (isn't it supposed to be like 1000?) The idle goes up and down a little (maybe 50-100rpms, not much at all).

I noticed a nice bump in throttle response, as well as some more sound, and a small increase in acceleration.

I didn't really think it was very hard. I was just wondering for a long time if it would screw up my engine.

Ok so I drove it to and from school today, and it grumbles now after I let off the gas, much like your typical sports car would do. Am I leaning out? And if so, should I worry about it? I can put everything back together really quick, but I kinda like the way it is. I just wanna know if it's gonna hurt my engine.

its not gonna hurt it at all. you should just take measurements, and put a piece of exhaust tubing where that goes. im gonna get a CAI for a 2.3 ranger and put it on my car.

Check your plugs unless you have a WB. If you see white you are running lean, or your heads cracked

Air Fuel Ratio, just measures a wide range (hence wide ban)
