Broke the MAP sensor off this little offshoot unit fitting the motor. Turns out my new ECU, the Hydra Engine Management System has an internal MAP so I'm deleting this elbow looking thing. This elbow, which mounts the MAP also feeds the brake booster and another vacuum line, is right up against the stock heater hardlines. I didn't get a pic of this but it's gotta go. The LS6 has this same unit but the LS2+ does not. I'm going to drill and tap vacuum ports somewhere less troublesome.
