Yeah.... you have some issues. That simple set-up should be in the mid to high 70's.

yep I bet your ecu is going into overboost mode
My 05 ecu did not like any boost over 11

I don't know what prop I got the ski from a guy said he had a different prop and new wear ring. Max rpm is 8100 As for the nozzle i don't know what it's for it was on the ski but it's aluminum and say r&d. I'm new to the seadoos. I thought it should be faster. But what could it be.

I raced a guy this wknd who had those mods on his 04 RXP. He beat my RXP-X which has consistently GPS at 68 mph.
I let him use my phone GPS And he also pulled 70mph. Temp was near 90.
i believe he said his max RPM that day was 7950.
Here is the thread about that.

voltage clamp or v-tech ecu flash
I found it using the cmd my injectors were going to 100% DS

The stock 05 ecu does have a MAP sensor limit at right around 12lbs where it locks the injectors open..... but without a CMD it's a non issue. An 05 RXP with nothing more than an X charger, external IC, prop, FPR, air intake, and 42# injectors should run 75-78 mph easily.
