Congrats! Great build and clean installation, very OEM-ish looking!
Your 7psi of boost just got something like 50% more effective. What sort of software are you running? As is been updated since the addition of the A2W IC?
Do you have any measurement device or check light to ensure your pump works or to keep an eye on the intake air temps? Curious about how cool the water can be kept in a city/highway driving conditions.
I guess you are currently running water in the liquid part of your system. If you want to keep the inner part of the system clean (and efficient), you could try out glycol/water mix.
