I spent a while on Google trying to figure out Normal vs. SAE dyno numbers. I think I understand how this works.

Normal is real time, right then and there, current conditions. Right?

SAE is a calculated number for the "perfect" conditions. Example: temperature, altitude, humidity, etc.

Well, I got my 2013 GT dynoed this morning in Houston. The car has a 93R Bama tune with a JLT CAI. Conditions were 75 degrees and 83% humidity. Not the best.

Apparently the tech who ran my car didn't realize the computer was set to normal, and my WHP went in this order during my 3 pulls.

389 WHP, 386 WHP and finally 391 WHP.

But when he set it to SAE it said I have 409 WHP and 390 TQ. He said all shops go by SAE. Is that true? I asked him, so when people ask me how much HP my car has, do I say 391 or 409? He said 409. I also saw another member on here saying his GT posted up 408 HP, same mods.

Right after me a 2015 GT with a Bama 93R and airaid CAI dynoed in twice. First was a 408 and the second was 411 HP via SAE. So I'm not sure how we were so similar.

What numbers should I go by?

I'd personally go with the highest lol. Or what ever the printed gragh says, as it is proof. But a dyno can be made to read anything, a 1/4 mile time slip won't lie.

I've decided I'd love to brag a little and say the higher of the two, but 391 is what it made that day without correcting the weather. And in Houston, we will never have the weather to get my car to 409.

Thanks for replying.
