Well, since at full throttle vacuum is zero for NA cars and positive (boost) for cars with turbos, this wouldn't be an issue. At full throttle the vacuum advance will not be effectual anyway, as it is a means of advancing the timing during cruise (part throttle) for enhanced efficiency.
Be that as it may, you apparently have a problem, but since you apparently have full boost I can't imagine what it'd be without other info. Can you describe the phenomenon in detail, comparing before and after? Was there any service or other event that coincided with the decrease in performance?
