It can go either way, just depends on how you spec out your kit. I went towards the high end (this one) because I wanted to buy it once and never have to worry about upgrading, altho you can get a basic kit from them for half that price.

I bought the CMGS kit because it is the most tunable. Its my understanding that the basic kits which use a boost switch, merely turn on when you hit your desired boost level. The CMGS & VC2 are both progressive controllers. This means you set a start point (say 5psi) where they start injecting, and progressively ramp up injection rate as boost increases until it gets to 100% duty cycle, which you also set. For example, I have mine set to come on at 5PSI, and to run at 100% at 20 PSI. The controller will progressively inject more until it gets to 100%, whereas the simple boost switches are just on/off. This actually allows me to inject more water since it doesn't inject at 100% at 5PSI like it would if I only had a switch.

The main difference between the CMGS & the VC2 is the controller, the CMGS is a shaped like a standard 2 1/16 gauge whereas the VC2 is a big square controller. Functionally they are the same.

Both the CMGS & the VC2 can use the Failsafe Control Box (FCB or FSB, same thing), which is basically a brain that stores info about your system. It is designed as a secondary failsafe because if it senses something out of the ordinary it also will shut the system down and tell the controller to display a specific error code. I like it because it is basically a second system monitoring the injection, to make sure nothing goes wrong. Not required unless you go big with 2 injection pumps and 2 nozzles. But that's the big boy stuff, like 350 HP and up trucks, not what you or me have so again, not a requirement.

My kit also has a solenoid instead of check valve. The idea here is, the controller must turn on the solenoid in order to inject water; this means there is no chance of the system dripping into the intake when the engine is off or im parked on a hill, etc. Basically eliminates the chance of accidental hydro-lock. Also nice is that if something goes wrong, the controller drops the ground, which shuts the solenoid down preventing the pump from injecting anything.

The cool thing about their kits is you can buy a basic kit now, and then just add components to it later if you wanted to upgrade. Id recommend either the CMGS or VC2 even if you get a stripped down system because the progressive injection is badass. No matter what kit you get, upgrade to the solenoid for the comfort of knowing there is no check valve to potentially fail or leak through.

I would not bother buying a tank from them, id get one elsewhere since you can get more for your money that way.
