Like everyone has said there are to many variables to give you a good answer. What color tip are you using now? What kind of
soap "Mfg." are you using? If your not happy with the amount of
soap or the show you have out in the bay increase the tip size one size up and see if that doesn't give you the results your after. I have my
soap set so it looks like spray paint coming out. The high pressure
soap is mostly for show.
