surging / intermittant boost cut out on highway ???

My '99 9-5 (turned 125K yesterday) 5spd has been hesitating intermittantly particularly noticeable at highway speeds. Seems to happen when boost is up, then by boost gauge it will drop / flutter, then back to normal.
Seems to happen whether accelerating or steady throttle.
DI doesn't smell, and I'm not sure if it's ignition, turbo, or fuel. Fuel system has been getting cleaner every 5K or so.
Car has not stalled
No check engine light.
Plugs are right, but haven't been pulled in about 10K.
It seems to be happening a bit more lately, combined w/the no ac makes me a bit nervous on the long hauls. Still like driving the 9.5 MUCH better than the honey's vlvo 850!
Any tips on tracking this down?
TIA,
m
