Point being different dyno's, different operators way different results, no baselines in either case, so no real way to judge gains. It is difficult to make an informed opinion on a tune based on a one-off dyno regardless of what the results say (good or bad).

I agree one car is not enough of a sample group to make any concrete decisions.
But that said you have a tuned file in mustang (what the baseline is in) and Dynojet and the second tune in Dynojet You can back into what the new files curve would look like compared to the baseline.
It would be nice if the OP would post the files when he gets home.

One would think that VS/Evolve woudl encourage if they are so confident in their tune. Heck they could even show up and supervise if they have any concerns.

Not when you're making changes to the map based on the info that dyno is feeding you. You want one that you've worked with before.
