Default Dyno Sheet question

Bike is a 2017 CVO with 114 engine. Did RS468 cam with D&D Billet cat pipe. When I first had it dyno tuned the numbers were 114/131 and that was a canned map from Fuel Moto. Slight hesitation in 2nd gear. Decided to have it tuned today and the bike runs awesome. Better than before. He did a 4th gear pull. My question is why are the numbers lower now after a proper tune? Was it because he only did a 4th gear pull? Are some dynos that different? The curve looks great to me and so does the af ratio. I really don’t care about numbers was just curious. Thanks for the help

Oh ok, I wouldn’t sweat it too much as long as the bike is running well, Different dynos on different days and conditions will never be the same. There is a term for Happy Dynos as well, some of those always read high.

Absolutely. A good in-person tune changes everything. Numbers be damned, if you are happy, ride the snot out of that thing!

Small changes occur from running in 4,5 or 6, the higher the gear the higher the readings but the engine did NOT change. There are so many internet dyno's these days, its hard to tell what's what anymore. As others have said forget about it and if the bike runs and rides better that's all that counts. Go enjoy it!

That’s a good looking graph, power available where you’re going to ride most of the time.

I'd be happy knowing the bike now runs the way you want it! Like the guys said, different dyno different readings....now go out and ride it, and ride a few miles for me too!
