They were there, just not as pronounced. Mods, especially turning up the boost, tend to exacerbate any existing issues.
I had attributed the slightly rough idle to the intake valves at that point, but now that it has gotten worse, I would say fueling or ignition.
My guess in order of most likely to least likely would be one of these
Coil(s)
Injector(s)
Fuel Pump
Dirty intake valves
