The LT4 is rated at 650hp @ 6,400 rpm. 5200rpms seems way too soon to shift, you wouldn't be hitting your peak power.
Looking at a hp chart of the LT4, shifting at 5200rpms would put you at about the 550hp range .

The idea is to keep the throttle open, so intake manifold pressure stays high during the shift so then you can have full power immediately as soon as clutch pedal is released.

Does a 5th gen LS3 have no lift shift? i.e. '15 1LE?

This happens when the HP at the rpm you shift at is essentially equal to the HP at the rpm you end up in . . . assuming that you have enough headroom above peak power rpm before encountering any rev limit to do so. If there is an rpm limit getting in the way of the above, just under that rpm limit would be your optimum shift point. Keep in mind that the best shift point for one of your shifts won't necessarily be the best shift point for any of the others; best shift point varies a bit as the spacings between transmission gear ratios varies. Wide gear spacing will want you to run the lower gear out to a higher rpm than close gear spacing. Rev limits permitting. Norm

I used the feature several times now on my 2017 SS manual and it works exactly as advertised. I look forward to testing this out at the track next year to see what kind of gains I will see.
Thanks again, Al, for the detailed explanation! The 6400 RPM target speed was so close to the 6500 RPM redline that I thought it might not be working as intended. I'm happy to see I was wrong. In future, I would definitely recommend putting this level of detail in the owners manual or performance supplement so more owners will take advantage of existing features.

I’m psyched to try this next season at the track, may be good for another tenth or two...

No real gains, as it cuts a tad bit of timing on the shift. Mainly just easier and more consistent.

I'd expect a small difference in the naturally aspirated engines and a bigger difference in the boosted engines.
