If it could prove to be a strong performer in the 6-8k range, that would be great. Although the losses sub 6k on the graph posted do seem quite considerable, more so that any tests of other intakes
Although how it would fare with other builds etc...who knows. One graph doesnt tell a full story...although it's the only one released, so you could assume from that it is one of the more flattering ones ! Which might raise even more concerns

Compared to the billet intake manifolds that are designed to cope with 30+ psi boost pressures and have even distribution of air per cylinder, yes. Every intake manifold has a target market and there is no one size fits all, except for stock intake manifolds in 90% of the typical boosted combos out there. LOL!

And don't proper LS6 manifolds even go for $3-400 now ?

From a flow standpoint, restrictions, etc., it is not a good manifold design because the air flows front to back, then up, then 180 degrees back down, which is unlike any tunnel ram manifold that is a known HP producer. BTR is a copy of shearer and others while trying to improve fitment into various chassis. Their own graph shows it is down on HP in a boosted application from 4500 to 6200 and likely also in the lower rpm ranges is a clear indication of not only flow issues, but distribution as well IMO because you won't have nearly the distribution problems if you have good flow, possible, but not as likely if you have poor flow. To complicate the issue, the more boost you run the HP increases, but at what cost, more boost/hp developed? Likely event, which is not good. Customer service is a big thing, pissed off customers are impossible to get back, just ask me because I'll never go back to BTR for jack after spending 20k and getting jacked!

It follows the design of a dual plenum intake design which the Shearer does also, which is a design decades old. So nothing new whatsoever. And the main intention is to offer more even distribution to each cylinder.
It does seem you've failed to comprehend those simple basics...
But of course as a short runner intake, it was never going to perform well at lower rpm's. That was fairly obvious from the outset although many many have hoped otherwise and it seems have been proved wrong.

It is not a copy of anything, because nobody else makes one like it.

You could say every single intake manifold used on a car since the first car was produced....was a copy, so it is a nonsense argument, perhaps even more so from someone claiming to be an attorney.
And there has been no info posted of internals to state whether runners are unequal length or otherwise.
But yes the evidence so far in terms of performance.....that is the biggest disappointment of all, because it is poor.

Everything has it's place, including this manifold. For someone who races their car, shorter runner intakes are better because it holds power higher in the rpm range, which this intake shows. So to compare apples to apples, you have to look at other manifolds that are designed for the 6-8k range, and then compare how those are with packaging, fitment, price, etc.
For a street car, 2500-5000 is more important to some, so this intake is never going to be on their radar, nor any other short runner intake for that fact.
Like anything, figure out what your goals are first, then pick your setup to acheive those results.

The dual plenum isnt out yet, but if you'd read any of the thread you'd see it is almost ready for sale. And given the space constraints and them trying to keep it a low profile, it wont be a large plenum either.

For people who thought this was going to be a better, more cost effective intake for your bolt on LS1...this is not that case.
There is only so much physical room under the hoods of these cars....only so much room you have to work with.
These engines have been around now for almost 20 years(cathedral)and if you think someone is suddenly going to figure out the magic bullet that makes 20 or 30 more HP than the FAST or MSD for a N/A engine....
It's not gonna happen.
And I won't even bring up companies like BMR copying Strano's springs or NO "borrowing" idea's from NX...but I digress..
