After finding out that the USDM car will indeed have the 4.10:1 rear end ratio, I was curious how it worked out when mixed with the HKS DynoJet data. I tried my hand at Torque to the tire contact patch chart through all 6 gears, using a visually transferred power curve from the HKS video. The HKS video has been interesting as it markedly differs from the advertised power curve, falling off sharply at higher RPM. Does this represent final engine spec? Who knows 'til production models start hitting the dynos, but for now, here's my graph. I'm using 844 rev/mi for tire rolling circumference, FWIW.

Notice that for peak acceleration, you'll need to:
hit redline [7450 RPM] in 1st
upshift at 7250 in 2nd
7K upshifts in 3rd and 4th
final upshift at 7250 from 5th into 6th [at 130 MPH, mind you]

This is strange for a gasoline production car, to have to upshift prior to redline to get peak accelerative force. Hopefully the production car will breathe a bit better at the top end of the RPM band. Note this was taken from the "wheel HP" data, so drivetrain losses are already approximately accounted for. The only thing missing is aero drag implementation, something Deslock already impressively did in his previous charts.
