wasp, this sounds like an issue with your boost map and parameters.
keep in mind to sidestep all this stuff i just let my utec run the BCS in totally open loop. ie, 50% throttle = 50% DC, 100% throttle = 100% DC. it has no "target" boost level and will do nothing to adjust those hard-coded duty cycles.
i, personally, have never successfully tuned an oem ecu to act in that way. while dabbling with it i experienced behavior similar to that which you're reporting. by their accounts, others HAVE been successful, and may be willing to let you in on their boost control parameters.
