One thing I learned is good bottle pressure of 1100 psi or higher makes a world of difference. On the first hit the mph was 121, but next pass with lower bottle pressure it only hit 114 mph. I replaced the bottle and mph went back up to 121, then down again on next pass. I wouldn't have figured that out if they had not let me run it for four passes.
