Fuel injection? Open or Closed loop?

Depends. Usually more in cool weather. In my case, FAST XFI (with the straight line across the Manifold Air Temp correction table/"map"), "compensated" a little too much.

I guess some dyno rooms could have the inlet air temps adjusted that much?
I have to do it the hard way.
