I'm going to be finally converting my car from a Hallman MBC to Grimmspeed 3-Port in hopes of getting the turbo to spool a little quicker and hold boost a little better up top.

Question: Who is running a 3-port BCS on an external wastegate setup and how do you have your hoses routed? I've seen conflicting diagrams compared to those provided by Grimmspeed. The instructions I received showed the top port of the EWG going to Port 2 and the side port of the EWG teeing off a boost/vacuum source then running to port 1. Just looking to hear from those that run this setup to see what's worked best for them
