Questions about 2D before purchase

[l2r99gst]

I am thinking about installing a water or water/meth injection system on my DSM. However, I won't install a WI system without a failsafe within in the system. That's why I like the 2D, because I could wire it to shut off my electronic boost controller when a clogged nozzle is detected.

Anyway, in my limited research and listening to experiences from others, I am not sure if the pump in the 2D will suffice for my application, but if I don't use the Aquamist pump, then I won't get the clogged nozzle detection capabilities.

Anyway, here are a few numbers for my car:

Currently, I have only 650cc injectors, which I may upgrade, but for now, they are OK. A little more boost and I will be at 100%IDC. So, if I do a few quick calculations:

650ccx4=2600cc. Let's say a 15% WI. That is .15*2600=390cc. Can the Aquamist pump handle this amount? What if I want to go to 20% or upgrade to larger injectors?

Are there any other possibilities to still use the FIA2 with another pump?

Thanks,
Eric
