It should have been dyno'd in 4th (1 to 1). I would think the results would definitely be skewed (I don't know how much, though). I would have them run it again.

I have seen the HP numbers are lower if dynoed in a gear that is less than 1 to 1. Your car should show higher if you redynoed in 4th gear. The standard on chassis dynos is to dyno in the gear closest to 1 to 1 which is 4th on the 6 speed autos.

No difference whatsoever on a load bearing ("brake") dyno.
On an inertia dyno dynoing in a lower gear will do the same as dynoing a car with a higher final ratio; it will show slightly lower power numbers.
