You want to use the IM source as it'll tell you the actual pressure at the motor, not what the turbo is seeing. There will be some loses along the way, mostly from FMIC. The WGs lines from the IM have to remain connected because that is what is supplying the pressure to open the WG. The pressure source line from the EBC is going to connect to the top of the WG (the banjo bolts Sasha tells you to leave open to atmosphere in the instructions if you are not running boost control pg 72) adding additional pressure on top of the WG Spring to prevent it from opening until desired boost level.
