I. Have the bottom port running into the regulator
is this the correct way?
No.
Try this first:
If you are using the regulator,
BOOST pressure has to enter the regulator in the "
IN" port, and the "
OUT" port gets hooked up to the top of the waste gate actuator.
DO NOT PLUG ANY PORTS!!! This will make the gate completely inoperable.
Now, if the way I explained works for you, great.
If you want to try the way JGS says, then you can hook it up the way you have it drawn...BUT, you have to turn your regulator around. BOOST pressure from one port of the tee to the top of the gate, and the other port of the tee to the "IN" port of the regulator...then connect the "OUT" port of the regulator to the bottom of the gate actuator.
