Do you think I still have a leak?
Thanks a lot.

Yes, just not as bad. When the engine is running in closed loop, vacuum for the SPT is supplied from the engine intake (the port on the driver side) The SPT vacuum pump is to open the SPT when little or no vacuum is available from the engine, i.e. WOT for sustained periods.
It's not something that urgently needs resolved.
