Normally it could lead to a couple of % difference, but in this instance the ambient temps are very mild and I doubt that SAE numbers will be more than 5whp.It isn't a constant difference that you are alluding to. If you dyno on a particularly cold day, (colder than the "ideal" target of SAE correction) the uncorrected dyno numbers will be higher than SAE and vice versa on a warm day. But the biggest factor will be what the dyno operator input for the elevation. Some use that to pump up the #'s to keep customers happy, but that is only for the STD #'s and has no bearing on the SAE #'s. I believe the OP is in a low elevation area (under 1k'), so unless the dyno operator tried to fudge the elevation, the numbers wont be all that different.
Thanks for the info, I didnt know the majority of what you said in this post ...In my instance the uncorrected was much higher than the SAE corrected. I saw the uncorrected is like 101% and SAE was either 97 or 98%. I was at low elevation and similar temps and the difference was 3% with the numbers I posted being SAE, 3% lower than uncorrected
