I'm also running the biggest nozzle provided in the snow kit and doing a 80% blend. I think it's a pretty sweet setup. I love the pull. I have used like 3-4 gallons of methanol in less than a month, but Dang has it been worth it! Thing hauls! If a smaller nozzle with better atomization makes more power then I'm open to changing!
P.S. I have stage 2 and running 8 psi as a turn on and 12 for full pump. It works pretty well. Only turns in when I really want to get on it, which is what I want anyway.
