Like others have mentioned I think the dyno is reading low. I would trust Lund, they have no reason to not give you all the hp they can. Other tuners will only be able to turn the timing up some more, resulting in more hp, but also potentially pushing it into being unsafe for the car.
The 401 base reading seems low, and I don't think it would have gained anymore looking at the graph, even if it was revved out to 7,500. When American Muscle did their dyno video (500+rwhp with bolt-ons) their base dyno run was 437. So even if your car made 410hp later in the rpm range, they still had 27+hp on your base, which would put your final number at 522, which is 11 more hp then their final number with FBO and e85.
American muscle had a really high reading for a fbo mustang gt. And when you adjust to their base (ignoring scaling) you at least make 11+hp over them, and maybe even 20+hp depending on what your car would make at 7,000rpm. If you assume that the numbers are scaled bigger than you made at least 18+hp (assuming your car makes 410 peak base) and possibly 30+hp (assuming your base only peaked at 401).
Dynos aren't the same, the correction factor isn't the same, and while big numbers sound great and make us hopeful, the reality is some dynos hand out bigger numbers than others. Even though I want my car to make 520+whp when I'm done, if my dyno is like yours I will make probably 490 haha.
Like others have said you made 90+hp over the base and that's what you should be comparing to other dyno graphs/numbers.
