| I am the kind of person that always likes to have things as clean and efficient as possible. I have always hated the manner in which the Profec B has to be installed on our Z's. I just think that there is just an excess of vacuum line for the whole set-up. The other day I took my Profec B apart and saw that the big black box contains two soleniods. These soleniods are wired together in parallel in a two wire circuit. (refer to pic #1) Therefore, both solenoids are working at the same time via one signal from the boost controller. 
We all know that the stock setup (more or less) for a TT is something like this. Where pressure signal from each sides charge pipe runs to it's respective turbo to control and regulate the boost. 
The Profec B requires us to set the car as like so...joining the two signals together and then spliting them apart again after the BC. Not to mention the fact that to do this, you must run alot of vacuum line to accomplish this. 
With the modified set-up that I am thinking about doing, it would require "extending" the wires from one soleniod to the other and separating them. Placing one on each side of the engine. This setup still keeps the two soleniods in parallel AND minimizes the need for all the excess vacuum line. The controller will still activate both soleniods as it does with them contained in the black box. 
I think that overall, this set-up would be alot more functional and increase the overall efficiency of the BC. Any thoughts or opinions are most welcome. thanks
