You can see right on the graph that the correction factor is STD not SAE.
I have no use for non SAE dyno's as there is too much variance in results above and beyond the variance already involved in dyno testing.

They don't just account for temp but also humidity and other factors as well.
(Air pressure/Altitude etc.)

I can see on your test that the humidity was 52%, thats very low, I would be lucky if I ever got a day that dry here. Its 100% today.

My car has headers, cai, and the b30 manifold and made almost 190 to the wheels and your saying you made 2 whp more stock... give me a break. Maybe you have a fine factory example but no car will have that much power increase over stock randomly.
