Interesting...
Where did you connect the vacuum canister to and did you happen to measure/view the brake booster pressure or sensor voltage?
(I assumed you didn't, but wanted to verify)
I'm going to go for a short test drive and data log the throttle position, MAP and brake booster voltage while driving around under different engine loads.
AND with the engine off/ignition on to see how quickly the pressure in the brake booster changes.
The rate of vacuum drop (pressure increase) may be helpful to troubleshoot this issue. -OR- it may not be helpful at all... You don't know until you look
