That impeller is the way to go. -
What is the difference between the 11/15 and the 13/19. They both say increased hole shot and top endComment

I am no expert. I did the RIVA Stage 1. My ski went from 57 mph/7000 rpm to 73 mph/8300 rpm easily. That's on the speedometer, not GPS. Check out the RIVA Racing website. There are actual experts on Greenhulk.net---this site, who can speak on the difference between the 11/15 and 13/19. I am also interested in learning about the difference between the two impellers. Good luck with your search.Comment

The 11/15 is the way to go if you reflash the ECU with the MaptunerX. If the ski is still running the stock ECU then the 13/19 is the correct impeller
