I think you should get rid of alot of those 90° corners and put bends there instead .. and the whole thing looks a bit messy to go into a bike frame , wont be to much work to compact it abit :D[}:)];)

Missing from that schematic is a boost referenced adjustable fuel pressure regulator. The vacuum/boost line can be either side of the throttle blades, engine side of T/B's will give boost/vacuum signal, or plenum side will give boost signal only.
At least, that is what my setup has. The ECU can voltage reference the fuel pump in some instances to give a particular volume/pressure, but mostly AFPR's do this job, as far as I know.

would that only be beneficial for high HP applications Ben?

No you should have a adj regulator anyway to keep the fuel pressure right through the whole range .. other wise it'll be rich down low in the boost range and lean at the top

[Booster]

As Benz says , reference the fuel pressure.
If fuel rail pressure is 43psi then you put 5 or 10 psi boost into the inlet manifold without referencing the regulator you are effectively reducing the fuel pressure 5 or 10 psi

Awesome, thanks for the info!

There's a few extra bit in there that I don't use.

Mass Air Sensor
BOV dump tube (mine vents into atmosphere)
Intercooler
Catalytic Conveter
And the coolant set up. (Although my turbo is designed for water cooling, I have no water on the bike, so I just blocked it off.)
Cylnders 3 & 4 also don't apply to my bike:D

I do run a rising rate fuel pressure regulator on the return line from the fuel rail to the tank.
