    He added a GPS Adder and Cruise Control Max in the Speedometer section. I maxed those out.
    Also in Engine:Torque Management:General added some break-in torque limits. I maxed those out also. I'm guessing those torque ones were the key to getting more RPM out of this thing as before the changes it was stuck at 8040 RPM on the speedo and bouncing around that in a log file but I could go faster than the stock speed limiter.

I just put it in sport mode and went for it. Didn't trim it at all as I was going. This machine has stock impeller and only mods are a 4" air intake plus a catch can.
    Yes, please elaborate..

    I must be missing something, went back in and tried all that, still hits a wall at 8k rpm. Have transient rpm set to 8300, break in torque limits disabled, all speed limiters set to 150km gps added and cruise set to 150km.

    The HPT platform is so new I have found it very difficult to, Number 1, find someone that's willing to help, 2 find someone with experience with HPT software for the SeaDoos, and number 3, someone that has an MPVI2 so they can see your tune and help with changing it. That is not possible with the older models without a tuning license. So in other words good luck with finding the answer to your question, there are many here in the same boat. Lol
