Vrod Muscle cams dyno sheet

Just got cams and a bigger throttle body. Already had the Vance and Hines comp exhaust and a power commander 5. Before the cams I had 78 tq and 118 hp after I have 84 tq and 135 hp. It sounds good but the dyno sheet doesn't make since to me. I got it done at the Harley place and they said they never had to change the map does it look ok to you.

did you ride the bike to test? it has a dip in the red power curve at 3k rpm (that's the stage2 run) normal if they didn't change the map and they should've tuned that out

every bike is different,why not make a custom map for it and smooth out the VE tables.

mine pulls like a train with stage 2 cams from 2k to redline without flat spots in the powerband

Do you have your dyno sheet so I can compare and what does your map look like

Just curious, what tuner are you using?

First thing you need to do is check with the dealership and find out what model of dyno. Is it an inertia dyno or a load cell? Without that bit of information everything else is pure speculation.

I'll speculate at this point that your dealership has no idea how to tune a bike and their dyno lacks the capability to do it correctly even if they did know.

Well it does have some dips in it that could be better. As long as it runs good and you are happy with it, place the dyno sheet on the roll beside the toilet. That's where most belong anyway. I've seen many pull some great numbers and run like a shithouse in normal operating conditions. More to a great tune then the peak numbers. Getting both is the holy grail.

no I tune my own bike,I'm waiting on an opportunity to do a free dyno run when I have the chance (just to know how much power I make)but it runs so well I don't need a dyno tune

After riding it some I'm very happy with it just wasn't sure if the dyno looked normal or not
