JB4 Dyno Results 5/30/19

First I have to say this is some awesome information. Thank you for taking the time and resources for gathering this and putting it together.
I was taking a look at it more closely though and had some questions about the data and what it's showing.

First the Baseline.
All other dynos pull all the way to the 6250 rpm, but the baseline stops closer to the 6000 rpm. Why?
Peak HP appears around 5600 rpm on this baseline dyno.

Baseline
343hp
395ft/lb

Now with the Stillen Intake was installed, the Dyno claims the HP is 356.1HP in writing, yet the HP curve never goes above the 350 HP line. How is that possible?
At 5600 rpm, the HP looks to be more like 345 hp & 393 ft/lbs, which is about the same as the Baseline

Lastly with the Stillen + HKS Plugs (Map0 - deactivated stock map), the 358 hp spike seems to be a random upswing right after 6250 rpm (remember the baseline run didn't even get that high). Is that really real? If you go back to the 5600 rpm max power region it only looks like it makes ~345hp again.

So after taking away that weird upswing, (and without overlaying the baseline to the Stillen), I don't really see any HP gains with it. Am I missing something?

You're asking about a dyno run that was done 6 months ago, in a 100+ degree facility, and with no significant cooling time between runs. If you asked me in June, i'd have an answer for you, but it's November. Additionally, I didn't know as much about the platform as I do now and knowing what I know now, i'd be more interested in the logs and AFR than for the graph. In fact, at this point, I wish I had never posted the graph. It's useful for me but that's about it and it certainly shouldn't be interpreted in any way to someone else's vehicle.
