Here an example of 4 pulls done on the flattest road I have available, the fluctuations are too big (also you can see my lean hump in the AFR and that I tried to make VD show load in the boost graph without much success):

To be fair, if you did 4 pulls on an actual dyno the variation between traces would not look too far off from what you'd see in your virtual dyno. but yeah.. you'd have to expect the virtual dyno app to be a bit off in terms of accuracy.
Carry on, good sir.
