Default Stumbing when started cold, goes away??

When i start the car cold and drive away, the car runs real bad. When on the gas, it has little power (i try to keep 1/4-1/2 throttle, no to <5psi boost and under 3k rpms until the gauge is out of the cold zone and the oil is ~90C). The car will still make boost, but feels as though something is holding it back. It idles bad as well, really lumpy like it has a HUGE cam. The ISV tries to compensate and smoothes it out a little. It only goes it after the car has sat for a while, even if it isn't all the way cold, but doesn't do it if you turn off the car and immedietly start it back up. No smoke or bad noises, just started a week or two ago. Any help would be appreciated, thanks.

Default I checked them last week, I wanted to make sure there was no moisture

around them that could be evaporating when the car warmed up and condensing later. Nothing found, no moisture, all plugs tight.
