Philip, where I dyno, elevation is zero, and temp is usually between 75 and 85 degrees (the reference is 77 degrees F), so the correction figures for my conditions are usually nill.
And it wasn't "a zillion HP" (is that really a number Phillip...COMON NOW!! I think you're pulling my leg??!! ;) , though a million HP is my real target, working on it!
