Sorry, Jet size question

[DSM16GSX]

Sorry, I know you guys must see a lot of jet size questions. I did as much research as I could before posting but I'd like to make sure I get the right size jet for my application.

I have a 91 Eclipse AWD Turbo. It makes 320HP @ 22psi boost on 550cc fuel injectors, 255lph fuel pump, big FMIC, and big 16G (36 lb/min) turbo. I am running a 100psi water pump with a 1S kit. I was thinking about a jet size between .6mm and .8mm. I don't have any real knock issues without water injection, but I'd like to bump the boost up a couple more pounds safely and run some more timing on 91 octane. I really want to make sure I don't go too large and have bogging/hesitation issues. I will most likely be running a 50% Alcohol / 50% water mixture. Any suggestions on jet size or water mixture would be greatly appreciated.

Thanks
