Help! 1s probs

[kack]

I have a Fmax turbo kit with Aquamist 1s system installed. My car was running great untill recently I have noticed pinging on load. I believe that something might be wrong with the water injection system. If the nozzel is clogged what should i do to fix it? What else might be clogged.

I've been using a 70% H20, 10% standard OEM windshield stuff(that was in the reservoir already, 20% rubbing alcohol mixture. Would this kill the pump? What should i do to test the pump?

Also, how do you adjust the Boost Switch? Is it set at 10psi from factory? Im running 9 psi max boost...so technically my water injection has never been working? Im so confused.
