Default 3rd....
Most dyno rooms don't even have adequate fan coverage for 3rd gear pulls...

We test in 3rd,4th,5th here...

If I had to recommend a single gear for testing, it would be 3rd.

Default I agree, we test in 3rd. Figure you are approx. 80-85mph in 3rd... most
dyno shops dont have fans that can simulate that kind of wind velocity and flowrates.

Does it matter which type of dyno that it is done in?

Default Yes, differences in both HP and torque. Keep in mind that differences will.....
be directly related to IAT and lack of airflow across the nose of the car.
