I need help guys...
Took the ski out today to start getting her dialed in...
I am running a 15/20 with an 82 ring on the RXT. The 15/20 has been touched but I don't know the specifics since I bought it used.
With a little less than half a tank of fuel I would go 77-77.5mph non-superman.......RPM's are down about 300...I'm getting 8200-8250 with the RIVA ECU which should support 8500-8550...
Where would you start? I don't have a boost gauge but was thinking maybe its time to get one? If I do get it, can I tee off of the RRFPR line from the block off???
Should I do that first, then get the 81mm and pitch prop...Or should I just go straight to 81mm ring and pitch prop...Or maybe try the 15/18 3 blade?

Not knowing the back ground on the impeller i would suspect of it. Try to borrow someone's 15/20 to try or start depitching yours.

Try a larger ring or NO RING....If RPM's come up to 8500's, then you know you have to get the prop depitched...THEN you can toss a 81 ring in there...

Do you have a stock nozzle laying around you can throw in just to try?
