the car is supercharged and you randomly started plugging vacuum hoses? Why were there open ones? One was not the BAP/MAP sensor that you capped?
Take some pictures and post them underhood
In General terms you need vacuum going to the folllowing
FPR
Brake Booster
PCV valve
Boost gauge
Boost blowoff valve
Cruise Control
HVAC controls
Charcoal cannister
with a supercharged application you normally want an open valve cover breather, cap off the breather tube and bung on the Throttle body and then a check valve from the PCV to the breather and the PCV and screen, or no PCV and breathers in the PCV hole and valve cover and cap off the bung on the intake.
