If you want to do the 2 stage then here is how I would set it up. Have a main line run into a w/m distibution manifold that has at least 5 outlet ports. Run four lines to your intake mani for the direct port. Run a fifth line to a solenoid block and then run a line out of the solenoid to the TB pipe. Hook a switch up to the solenoid and you can trigger it whenever you want while have the direct port working all the time. I suggest putting a switch on the controller's power line as well so you can turn it off, if you haven't already.
