1963 gt slant 6 turbo install and good ideas

Your wastegate line that you have to the intake after the carb should be hooked to the PRESSURE/Boost side before the Carb in the intake tract off the Turbo/intercooler.

Hook the line from the boost controller to the side of the carb hat. You will not be able to adjust your boost the way that it is. It is actually sucking the Diaphragm closed the way you have it.
