    2019 FX SVHO Stage 1 Questions

    Just tuned my 2019 FX SVHO with the Stage 1 tune & the Riva Ride Plate.

    1- Speedometer is maxing out at 70, is that normal for it to not show true speed above 70?
    2- RPMs somewhere between 8000 and 8100 when it is supposed to be at 8300, does the Tach reach 8300?


    I just want to make sure this is normal behavior? Top speed on my phone with full gas tank was 72.5 mph.

    coming out of a 2016 FX SVHO which went above 70 on the speedometer.

    welcome all feedback??

    Speedo sucks on the 19! It won't read over. I got 73 with stage 1 tune, just hit 74 with ride plate till it warms up and back down to 73... It wouldn't go over 8100 rpms. I installed a 13/20 solas and rpms won't go over 7800 but speeds the same. Wondering if the 13/18 would've let it rev higher for some more speed

    13/18 will do exactly that!

    Having same issue with Stage 1 and now Stage 1 plus with 13/18. Tried a depitched 13/18 from Dean and same result. Sent files to Jesus at Riva and told me all is ok with my ski and the tune but still need to depitch further to get the revs up, interesting that with 13/18 depitched and Stage 1 plus kit I still could not hit the speed, RPM, or boost limiters with the stock tune. Sent 13/18 stock impeller to Impros to depitch to 13/15 and see what happens, if I hit the rev limiter which I have set at 8650 with the 13/15 then I will add Lucky 13 to lower otherwise I am changing from the Riva tune.

    Please send Jesusg@rivamotorsports.com an email and include the VIN as it's displayed on your Maptuner. i want to have him double check the file you are using.

    Thank you

    After a nice dialog with Jesus @ Riva, it sounds like it is what it is. With the stage 1 kit leaving everything else stock only going to get so much out of the machine. it is a little too heavy. i think top speed is about 71-73 MPH, rpms 8,000-8200. The impeller will definitely need to be re-pitched but i am not going to deal with it. just going to enjoy the ride...
