Well most washer fluid is approx 35% give or take. The nice thing about the DO mix is just the fact it's consistent. The problems with running too high a water content is slowing the combustion down in the chamber. Just my opinion of course, but when you do enough testing to see that you can use a crummy mix to run a 2.8 pulley, yet run the same or slower time, the writing is on the wall....the more potent the mix, the bigger the nozzle. If you truly want to battle kr, then in this case an M3 would be just about right in keeping the temps down.
I don't have the controller set to any typical setting all of the time, it really depends on the weather, and how the car acts. Say that if I can run the car into the 5-7 psi range without the kit on, and then it starts to knock in the 8-10 range, I'll adjust the turn on point at about 6.....that's the thing I love about the progressive controller, is basically an on the fly tune capability. I'm sure its even better if you have the ICCU and you can tweak as you go. And usually when it comes on, I have it set to go full within 2 lbs of the kick on setting.
