Default How do my dyno runs look?

2019 Sportglide with Woods 22Xe cam, TBR 2-1 Comp S, SE Intake and V&H FP3 tuner. He said he ran it in 4th 5th and 6th gear in that order. Wondering why 6th gear had the highest torque.

That cam is known to hit hardest above 2500 RPM.

That looks pretty good to me. How does it feel?

In 6th gear the transmission is 1:1 direct drive with no torque loss. There are no gear meshes in the torque flow path.

A Dynojet dyno does not directly measure Torque or Horsepower. What it measures is acceleration rate of the drum on the dyno and calculates the numbers. With that in mind, the faster the drum is rotated, the higher the numbers it is going to show. So if you have enough power and Torque a higher gear will show more but it's not real, it however how people like to see things. This is just why you cannot compare runs on a dynosheet and expect them to be the same. It gets you in the ball park but that's about it for comparison purposes as long as you know how each was run.

It looks fat right at your torque dip of 2500 to 3500 rpms. I would like to see the MAP load in addition with the AFR there. I'm guessing these are all WOT pulls. But this would help if you wanted to fine tune your AFR tables. Another thing to note is what type of O2 system you are running. Are you running WBO2 or NBO2 sensors? Your TBR 2-1 I think might be contributing to the torque dip I'm wondering--the TBR comp S is the "shorty" ones, right?

Stock O2 sensors. Yep the shorty one. I figured from past posts that exhaust wasn't best for power numbers.

Yea that pipe is not going to get you there, but not for the reasons you think.

So I had that exhaust on my bike and I HATED it. On mine it had a terrible exhaust leak where the collector is denoted by the carbon trail where it slips over. Because of this design, there wasn't anything I could do to fix it on the pipe. I think the three-piece exhaust types aren't that great.

Do you notice any carbon build up on the collector on yours?
