I did initially see that it would build the pressure slowly, but after playing around with the switches on the smc box, 200 psi is litterally instant. i was extremely happy with the way the car performed. i was able to lean out the afr about 0.5 point and added 2-3 degrees more of timing.

I am seeing higher consumption of meth. I was thinking to upgrade to the M10 nozzle, but now i know the higher psi already gives me more meth.

The SMC controller I believe alters the voltage to the pump which can cause slow reaction time and a fulty pump after a while, might look into buying just a Hobb switch and a relay to power the pump. You will only get real precision with a HSV (High Speed Valve) from Aquamist. Acts like a fuel injector but for water/meth!

Good luck buddy lmk if you need anything!
