OK, I have a boost leak at the coupler to the throttle body. I have changed the silicone hose and installed new T bolts same problem. I can hear / feel air around the connection. The clamps just dont like sealing around the oval throttle body that well it seems. I have an A-A setup BTW. Question is about welding or sealing to the throttle body, ideas? I would like to get rid of this connection at least on my A-A setup.
