The ram induction is to increase the air intake pressure and oxygen flow....
As long as we're going off the rails here, pulling significant vacuum in your airbox seems a bit counter-productive. If the breather system depends on vacuum in your airbox, why would ram induction be a good thing?
UNLESS...the PC III usb is compatible with Dynojet's Auto tune module, with which you set a target AFR, install at least one wide band O2 sensor (they make two set ups. AT200 single channel and AT300 dual channel) and and wire it into a switchable 12v power source and the damn thing tunes as you ride. Pretty slick.You will love it if you are brilliant with the right computer software and internet savvy and trust that the aftermarket maps built into it are at least as good as the factory ones.
You can learn to tune fuel injection by altering the maps on a PC laptop computer program or if it messes things up just unplug it. Hope you have a laptop, it would suck to use a desktop.
