For me I think its easier from a hook-up and wiring aspect to let the HSF3 controller handle the initiation of flow and to monitor for tank low level and for me to make my flow failsafe in the ECU. Four wires between the HSF3 controller and the ECU make it a pretty easy hookup. It would be a lot more wiring to do a completely ECU driven meth injection system.

I may go direct port at some point but I'm looking for maximum IAT reduction now and could always add those 4 ports later.
