drilled the holes in the intake box

Clueless as to how you guys get such good MPG. I get 30 MPG highway and 11 city. Drove 110 miles today to pick up a midpipe and averaged 23.3 MPG on my 350 driving 100 highway miles and 10 miles city. When I drive city alone, it gets terrible especially when I drive aggressively, 8 MPG city. Don't know if it's all the stop signs and traffic lights but my car is well maintained.

Glad you figured out the situation OP.
Barring mpg aside, are you saying that the stock airbox from the factory provides too much airflow?
Why does anyone upgrade filters/intake tubes in that logic?

People upgrade their filter because either:
1) They are ignorant of that fact (see also folks who buy big brake kits thinking it'll make the car stop shorter when that's not the case)
or
2) They want a reusable filter they can clean and put back in instead of buying a new one each time.
People upgrade their overall intake for one of three reasons:
1) Again they don't know the stock one is already good
2) They want the ~5 hp gain you can get from switching to a smoother/better intake path like the Joe Z pipe (which doesn't add any power due to "more" air, because again the stock one already provides more than the motor can use)
3) They want more noise- this is usually the folks who stick a big cone short ram in there and either don't know or don't care that they might in some cases be making less power than stock by sucking in hot air with an open element filter.

I would say "more than needed" rather than 'too much' but basically yeah.

I would say that stock intake system has the capacity to provide more air than the motor can handle, but if small gains are to be had by a smoother, more direct intake path alone, it definitely doesn't do that as efficiently as possbile.
Good points on the cone filter and drop in too.
