Looks pretty good to me.
If you are going to base your purchase decision to spend $1k+ on a tune on an extrapulation between an "independent" dyno pull on a Mustang and a dyno pull on a dyno-jet at a shop with which the tuner has relationship, have at it, it's your money not mine.
Like I said, I understand there were likely some kinks to work out, seeing how this was the first US spec 335d to run the Evolve tune, but that is no reason to throw-out and discount a follow-up on an "independent" dyno where the original baseline and 2nd dyno were conducted after VS/Evolve made the adjustments. That is really the key data point that is missing; sorry if I am not drinking the Kool-Aid, YET.
