Stumbling under moderate boost???

I have an '87 9000 Turbo that has recently developed a strange stumbling issue. When I accelerate under moderate throttle in the 2800 - 3500 or so range with the boost in the middle of the orange I get a bad stumble and loss of power. This occurs especially in 4th and 5th gear. In 2nd or 3rd it is fine above 3500 and with high boost. This doesn't make any sense to me.
I've replaced the cap and rotor, the wires are fairly new, and the plugs are good. Regarding the plugs I've tried both the current set and a slightly older set with the same results.
