You sheets are not labeled.
Is the bottom one your baseline? and then top is final after tune?
What kind of Dyno?
Help yourself out a bit and pic up a cold air intake, should pic up a good 5rwhp or so.
If those came from a Dyno jet, I'd have to say the #'s look a bit low.
I've pulled 385rwhp on 2 different Dyno Jets at 2 different times, before my Kooks and uncated X-pipe. I had just Vara Ram, Larger air bridge and smooth coupler,Borla cat back, SVO 30's(don't really do anything for the hp they were installed for future projects) and a tune.
Now if this was on a Mustang Dyno then I would say your #'s are doing pretty well (still won't hurt to put on that CAI)
The biggest thing to look at here is not what your end result # is, but rather the difference between what you started with and ended at. If your sheets are top end result and bottom is base line then you gained 51-53rwhp(depending on which #'s your using) So a 52rwhp gain from headers, cat back, K&N, and a tune? Pretty respectable I'd have to say
Congrats and enjoy the new 50HP

To answer your question, are these #'s good?
Well I enlarged the pics so they were more clear and it looks to me that you have done headers and not done any tuning yet (or your tuner left ALOT!! on the table). You're running pig rich in your pulls, these results are not color separated so hard to tell what goes with which pull.
Your "better" run has a A/F of 12 to 1(vs the 9 to 1 of the other)......that should be closer to about a 13 average, 13.2 if you want to run it hard and squeeze it out and maybe as low as 12.8 to be good and safe. Can't tell if the operator let go at 5800rpm or if you dropped off at that point (open up the intake side and this will not do that.....ie a Cold Air set up of some sort.....you should still be pulling at that rpm) Either way there is more to be had with this in the tune and getting some more air into this motor on the intake side.
Regardless if your #'s are "good" or "bad" they are definitely short of what they could be.
I know that doesn't answer your question very well, but there is limited info to go on.
