Along those same lines with everyone doing it their own way……..
I assume you’re planning on a converter that flashes in the 5000 range……..
If that’s the case, I’d be starting the pulls about 1000 higher than what you’re doing now………and I’d extend the top of the pull to an rpm point that I’d expect to see at the end of track.

I’d be curious to see how well the curve hangs on.
All the tests I’ve done using that manifold(albeit an unmodified one) have had the curve fall off pretty fast. Way faster than a “racy” single plane.

The TR made more peak power(and it occurred at a lower rpm), but wasn’t that good when you got well beyond the peak.
