Jets/nozzles are pretty cheap. If you don't have a controller or way to up the flow then grab the next couple of sizes and give it a try.
You are running 50/50 and it doesn't look like meth is a massive amount of your fueling so it won't throw things off too bad to step up a couple. Still would recommend rechecking on a wideband.
How are you making boost? If you are maxing out your hair dryer that could be the issue when you turn up the boost.

the 2 nozzles are after the air to water intercooler and is about 12" from the thottle body i have it set to strat spraying at 4psi and fullload at 7psi i dont have a heat exchanger and thats the temps with out my intercooler on if i trun the pump on it wont go over 75* with ice but i do a lot of street drive/street raceing and i dont have ice when am on the street all the time so am trying to use the meth for the street and more octan i have no prob at the track with the ice
Ambient up to around ambient + 20ish degrees is nice, but not a guarantee. Honestly your 170 would make some supercharged cars jealous lol. Instead of shooting for a number, shoot for less than it currently is without causing bogging or screwing with the tune too much 
I use two stage. I have it come in around 12 psi and started with the recommended mixture which was a m14 so I used two m7s. I changed to 10 and 7 and hit ~ambient plus 10 degrees.
I think the recommended mixture is a good starting pioint and as mentioned should be used as a guide. I use -20 degree winddhield and then add a bottle of heet mixture seems good for me. The mixture can be debated forever many love 100% meth others 100% water both have their advantages mine is just flamable and seems a reasonable tradeoff for my setup
Good luck
