Seems pretty linear to me…
I guess there could be some mechanical issue I am not taking in to affect. It could explain a non linear relation.
I still think, there is something wrong with one of the dyno's if the delta is not the same (or very close).

If a car has 400rwhp on dyno A and 440 on dyno B, what would you expect dyno B to record if dyno A shows 420rwhp after an exhaust mod? Would you expect to see 460rwhp? If you would, that is an argument that one of the dynos is just shitting out numbers and not actually using the age old formula for deriving hp invented by Mr Watt. (by watching mules carry coal)
The issue here is most likely how the torque is measured. Not all dynos use the same method to measure torque so that would be the most logical thing to look at when certain dynos are known to always read higher or lower than another model, which by the way they usually read off by a fixed percentage, not a fixed number.
