Yes I agree the delta is important, but I was just concerned that my absolute rwhp was still very Low.
Could it be the correction factor that the operator used on the mustang dyno?
I am confident mine was a cf of 1.0.

Unless they took the engine out of the car, all dynos measure power/torque at the wheels, and then calculate crank numbers. Which means you can pretty much ignore the crank numbers since they are just estimates.
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.
