Cloud, you might want to swap out your M5 nozzle for a M3, when i ran a M5 on my stock turbo with stock pump pressure i lost about 30whp avg. The M5 was too much for the smaller turbo, you might want to try the smaller nozzle to make sure your not bogging down your motor with too much water/meth. I'm running my M5 nozzle on my 50 trim setup.
