has your large nozzle shown to increase your timing advance? or did you use another method to deduce that the larger nozzle is better?

lastly, i do not understand your statement: IPP @ 4psi ... FPP @ 8psi
can you clarify?
i am new to water / meth injection but having alot of fun with it.

thanks for any insight you can provide.
the larger nozzle is better b/c thats what the horsepower rating is at. 375mL/min is for 300-450 rwhp. according to snow.

IPP stand for initial pump pressure. where the pump turns on
FPP stands for full pump pressure, where the pump is at 100% work.
b/w there is where is gradually increases so its not an on/off thing.

i have advanced timing on the meth map via the procede... (the AA chip can only retard timing another reason i dropped it)
