2020 Road King Special
SE 131
CR-512
S&S Lifters
SE Ventilator Extreme
HPi Shorty Exhaust

Thought the numbers would be a little higher, but I’m happy with it overall. Plenty of power and torque right where I want it. Dyno tech used STD smoothing though, not sure why. He did say that he thought the ventilator extreme was holding it back.

@VernDiesel
Still find it difficult to understand why tuners create graphs with different scales on the left and right. SMH.

What's on the right side here?
Or you're talking about other sheets?

No, your sheet. The HP and TQ numbers should converge at 5250 (it's a math thing. Look at other charts, you'll see them converge at 5250). I cant see the right side of your chart, but if they dont converge at 5250 RPMs then the left side scale is different from the right side scale. One side is used for HP and the other for TQ which is stupid.

It doesn't change the numbers, but it just makes the chart more difficult to read, and is completely unnecessary.

There's no right side and both HP and TQ are on the left - hence was my question.

Well there's something funky about the chart because mathematically HP and TQ should converge at 5252 RPM. Again, look at the other charts in this thread.

The tuner used HP/Nm instead of ft-lb for the torque.
