GM 3-port: VTA or not?
To Those who have installed a GM 3-port: Did you VTA the 3rd port or did you connect it to the intake pipe?
I know that the GruppeS 3-port instructions say to connect the 3rd port to the intake.
The GM 3-port does not come with instructions. So which way is better, VTA or connect to intake pipe?

VTA or not GM 3 port
I tested this on my car and found VTA ran a little richer, and a little richer spooling up after drop throttle in tuning logs. Acts like VTA BOV but much less so. You might spike a bit more so be aware of that if going from VTA to recirc'd.
So I concur with Brian.
Anyways that is like a boost leak, so you dont want that from that standpoint.
