Does it run right? Feel strong? Don't get too wrapped up in dyno numbers as they all read differently. Plus, I've had so many customers read online that so-n-so made such-n-such HP on the same combo, but be down by 30-40 HP....only to run .5 seconds quicker on the track. Dyno's are tools to measure...and all calibrated differently.
That is why I like road tuning as well.....Get a more rounded look at your car.
SAE or STD doesn't matter at all. It's just a conversion/correction factor. If all of your previous readings were measured in STD on one dyno and then you bring it somewhere else to use a different dyno and they convert it to SAE, in essence you have learned nothing...other than you wasted money on another dyno chasing a different number.

You are correct, but standard numbers are not what everyone goes by. So my car made 560 SAE and 582 standard. Should I tell everyone my car has 582 rwhp? No.

If you did, you wouldn't be lying. I could tell everyone I made 383 rw...when they look at you funny, tell them it was in newton meters. As I said, it's just a conversion factor and makes no difference what you tell people. When we dyno, we ask the customer what form they want the results in. And that suffices. Believe it or not, your output of 560 SAE/582 STD is the same number. If you tell someone the STD number, it only makes them have to do the math to convert it.
FWIW, a lot of folks use STD numbers especially on the internet...more specifically the import crowd. They like to publish STD numbers because they are usually a touch higher.
My weather 76*, 12%, 900DA: drop from 630 to 604rwhp SAE
His weather 74*, 6%, high 800's: increase from 520 to 525rwhp SAE
That's pretty damn close for weather.
Both dyno jets
IMO, has to the SAME dyno to even be really comparable.

That is our preferred method to tune. Car always tunes better with true load.
