Just installed downpipes, rough idle questions

I just installed catless downpipes. Easy install, but now I am having some issues with an incredibly rough idle. The car sputters and pops. I have a jb3 tune on it and when given gas the car smooths out and sounds nice. Any suggestions as how to fix this? The car sounds like its choking, obviously not getting enough fuel but how do I adjust that at idle?

On another note, has anyone ever replaced a turbo waste gate?
