Higher RPM
Low throttle
Without vacuum
Not sure how you would accomplish that combination, assuming I read the intent of your post correctly. High RPM and no vacuum can not really be accomplished with low throttle positions. Low vacuum is high load which means the engine is working harder. It's not really possible to have a high load and high RPM with a low percentage of throttle opening, unless you went from a high percentage of throttle opening to a low percentage, which would raise the vacuum reading for a short period of time until the inertia of the vehicle depleted and the load increased.
