94 aero-misfire under load/boost

I'm going to pull the plugs tonight, but a couple of days ago I noticed what feels like a pretty good miss happening once the boost comes up (particularly to the yellow/orange hashed area on the boost gauge). Obviously the car feels low on power and sluggish to build boost. The problem seems to be less (almost non-existant) when the engine is cold and gets worse as it warms up. It runs absolutely fine when I'm easy on the throttle, idles smooth, no miss under light/no load. Temp gauge reads normal, no weird fluctuations. My question is, is it likely the plugs or DI cassette or am I barking up the wrong tree? Car has 192k miles, 5-speed, no TCS.
Thanks,
Scott
