Can't really help you too much unless you gave us the code your car is throwing, I'm giving you a guess essentially when I say its the intake, wont know for sure untill you look up the exact code seeing as there are several that can result in the engine running too lean

System too lean... could it be saying "Bank 1 too lean" or something along that line? Cause if it is its probably throwing a P0171 code. Which for me was cause I went catless and put 2 defoulers on the rear and one on the front, but i swapped out and put only 1 on the rear and it works fine now. However since I have a tapped o2 signal up front coming off my wideband o2 sensor I have a P0135 code for a dead heater core on my upstream O2 sensor.
I have a RRM SRI intake, RRM Catback and downpipe matched with a cheapo LC-1 wideband O2...
Have you tried resetting your ECU and going through the learning process since you installed all the parts?

when you remove the cat, did you do anything about the rear o2 sensor? If not, that alone should throw a CEL because it'll think the cat isn't working and your spewing too much pollution. To counter this, it might cut fuel and run lean, thus throwing another code. Kinda sounds like what your describing...
simple check: put the cat back on, reset the ecu, and see if things go back to normal.
oh and a friendly edit: STOP KILLING LUNGS JERK!

You need a tune, plain and simple. You can't expect to throw a bunch of parts at the car and have it work perfectly right away.
The CEL for the cat is something that's going to come back occasionally, you're going to have to get used to it or buy a code reader to clear it when it comes up.
As for the system too lean, you're probably leaking air around your MAF.
