I have the Zex 75-175hp and was wondering what is the best placement of the nozzle for max performance? I know it says from 6"-18" But I just installed a C&L Trueflow cai and really don't want to drill a hole in it, let alone in the wrong spot. I was thinking of a spot in the silicone hose conecters?? (just seperate the cast pieces a bit) If that didn't work I could replace it cheap.
