My car is currently getting it's tune tweaked. Last time my car was dyno'd it was in cool, dry air. DA is around 4k now and tuner is saying not to expect the same kind of #'s due to the conditions. I thought dyno's corrected for DA?

Yes, it will do corrections for conditions but the conditions are going to make less power, sounds twisted but I don’t know how to explain it. Maybe this will help.

This one of the best reads on dyno’s, from engineers points of view, took me a while to find it. Basically it says Correction factors and forced induction don’t mix well and should not be used or at the very least believed.

Good stuff, thank you!
I have one but I'll have to wait for fall to see the before and after. Last time I did it was around 500 DA. Don't even want to know what it does in 4k DA lol

I agree, a draggy or Gtech is a great tool for testing mod changes. 60-130 times tell allot.
I did a 4.9X in DA close to 0. I'm going to try it soon but scared to see what it will do in 3-4k DA. I'm expecting a good bit slower. The 1 good thing is that it at least hooks more consistent in the heat.
