Your numbers don't look far off if they are in kW/Nm. In fact, they seem high. 288kW = 390rwHP and that's very high assuming the Mustang is a heartbreaker dyno.
But I would be most concerned about the smoothness of the curves. The S65 is known to have an absolutely flat torque curve between 3k - 7.5k. Yours spikes and dips in a manner that is not normal. Same goes for the power curve, you have a flat spot at 5.8k that's not normal.
Not sure who this tuner is but I would highly recommend you get a tune from a more reputable source.

The numbers are in rwhp..hence my rwhp of 288 is much lower than what I see on the s65 dyno database.
Could it be that the mustang dyno database numbers are based off a correction factor of 1.15-1.2? Hence explaining the higher rwhp numbers?
