    This page is to store dyno tuning graphs and accompanying info in the one place so people can get an idea of which mods produce what results for a particular engine. 

     

    This is my Roadglide with 103 engine, se ventilator, freedom 2-1 exhaust, se tuner and se 204 cams. The baseline graph isn't a true one as it has the above parts on the bike but with the se canned map in for stage 1 and without the cam change.

    I have always seen such different results and heard stories about happy dyno's and humidity and pressure fudging etc. So i decided to look into it a bit more here are some interesting reads and what to look out for .

    Yeah she goes pretty hard Hilly, extremely happy with it. Lifts the front wheel very easily just powering on, no dropping the clutch :)

    My 2014 Fatbob. 117” MMVT Build
    True and welded crank with 0.0008” runout at the  cam plate... lots of goodies internally. 
    Only done 20000km since this build but there is 115000km on the clock.

    MMVT Specials heads. SE 266 cams 
    I’m looking for more hp/tq
    But it’s as strong as it was when built. Had a power run on a different Dyno than was tuned on, and it pushed same numbers. 
    True testament to Ando at MMVT

    Might test with different exhausts down the track or take the comp from 11.1 up to 11.5 if possible. Give it another 10k km and see how it goes after that.
