So I have the ACE header dynoed (dyno'd?), but unsure whether I should start a new thread with my thoughts or just dump it here.
93 octane:
E-65 on ACE header, E-72 on JDL UEL header:
Big note about ACE peak numbers:
I did some inspection this past weekend and saw that a bolt was missing from the header to OP connection. Have replaced that and checked all the header bolts, which were tight.
Thoughts:
Peak numbers weren't really my goal, as comparing dynos from different days and different operating conditions can have such varying results. Instead, I want to look at the curve of the graphs. There's some notable things that pop out to me:
* The 3500 to 4500 RPM range yields a notable gain in both whp and tq compared to the JDL UEL. This is great for day-to-day driving.
* The EL sound really isn't as "Honda" as I thought it would be. I did enjoy the baby rumbles from the JDL UEL, but the ACE sounds great at the higher RPM, but the JDL FP and Dezod catback probably help with mitigating any rasp or lawnmower type sounds
* I'm initially disappointed with the peak behavior. The power drops off around the 6700 RPM mark! I'm regularly running 7000-7200 on track, so I'm a bit apprehensive that it dies off so early. I wanted to make sure it wasn't a tuning/tuner/install error, so I checked out some other ACE dynos:

One thing to note, CSG & Delicious Tuning are the biggest vendor/tuner combo for the ACE set up. On CSG_Mike's 2017 BRZ, the power band builds linearly through 7000 RPM.

tl;dr / Conclusion:
Because most of Delicious Tuning's customers are remote tune, there's not many data points on how their ACE tunes do, besides CSG_Mike and I believe one other Cali member's plots. Regardless, if one's set on the ACE set up, I would recommend to go through CSG and Delicious Tuning combo.
Now I'd be really interested to get my hands on a JDL 4-2-1 header and get that dyno tuned to compare.
