Very nice, are you using a window switch and bottle heater as well? I used to run a 125 shot (wet) in my 350Z back in 04. Zex kit as well. I had it set to spray between 3,000-6,000RPM at 90%+ throttle.
Don't spray for more than 15 seconds continuous your cylinder temps will get super hot, I stretched my rods to the point were they tapped the heads playing with a 911 turbo
Have fun!
