The day he had it dyno'd was probably a very low correction factor.. it was a pretty nice day to Dyno.
Here's a stupid question but maybe not because I think I just answered it in my head but Dyno correction factor which are usually a set bp, temp, sea level and a few other things.
Example my engine observed HP on one run was low 620s and like a 11% correction factor ran the numbers to 685 on that run.
How many correction factors are there dude ?
I think atleast 3 based on weather and altitude

There are several but no one I now uses any thing other that Standard Temperature and Pressure.

That’s 60 degrees, a 29.92 baro and dry air. That’s THE correction factor unless you care about other stuff. I’m sure some of its emissions related and such.

I know one of the other SAE correction factors is something like 72 degrees, less barometer and some humidity.

I use the STP correction.
