Do you have the knock sensor update harness installed? If not it needs to be.

This is the location of your knock sensor connector. The update harness will be a short pigtail harness that plugs between your stock wire harness and the knock sensor connector. It's about 8" long.


Other things i would look for are a boost leak. Check the BOV and all your plumbing connections.

i pulled it out of the water and ran it it revs to like 8600 or where ever the rev lib is but it does make any boost on the hose jerry let me know what u think i need to figure this out makes me mad all that money riva claims bolt on

So if I understand you correctly, without a load on the pump it revs to the limiter and makes plenty of boost. In the water it is a dog. Sounds like a prop problem.

Edited post, I read his RPM's wrong. Thought he said 6800 out of the water. nmaD aixelsyd.

don't blame it on Riva dude! Plenty of people run this kit with no issues.

You will not make boost running it on the hose. The ski has to be on the water and under a load.

Did you take my advice in the above post and look to see if your ski has been updated with the knock sensor update?

the boost gauges doesnt register boost out of the water only vac maybe i got a bogis riva stage 3 prop

Jerry's probably right. Knock sensor update harness is not installed.
