Same scaling?

 

[1slow03Cobra]

You mean different dyno? Yes but both dyno jet. Can't be off by that much. Lol

 

[oneslo5.0]

No, both corrected power? You sure one wasn't un-corrected?

 

[1slow03Cobra]

Corrected?

Corrected numbers take into account the weather. It's a way for dyno operators to skew the numbers a tad.

Two different dynos and a year apart. Things change. That's why they say dynos are just tuning tools.
