Don't T your FPR. Ideally, you don't want to T any of them but that's just the way it goes when there is not vacuum ports. You could always run a vacuum block but your MAP and FPR need dedicated sources directly from the engine for best performance.
Personally, I've always tapped my compressor outlet for a barb fitting to use as my wastegate source. BOV and boost gauge have always gone together. You could even mount the MAP sensor on the strut tower or firewall, tap your lower intake manifold plenum for a barb fitting, then run a hose to the sensor.
