  • 07 R1 dyno tune with exup wired open

    Hi all,

    I had my R1 dyno tuned today, running a PC3, k&n filter, standard headers with exup valve wired open, m4 y-pipe and gytr slipons.
    Am now producing 165.5hp @ 12k rpm and max 82 ftlb of torque.
    The power curve dips considerably from about 6300 -7000 rpm due to the exup being wired open, this has definitively proven to me that the exup should remain a part of the system untill a full race system is installed.

    Hi Noel,

    Did you end up getting a full race system? I'm thinking of removing my EXUP due to possible faulty actuator. Won't cost much for a second hand actuator, but weighing my options up.

      Did you do a before/after dyno run?

        Since I run a full exhaust on both my R1s I forget what they feel like with the EXUP operational.

        However, when racing I don't think the revs drop below 7500 -8000 rpm
