N55 DCT Shift Points with Pure Stage 2

[ganque]

Hi Everyone,
I've been trying to beat my personal 1/4 mile record using my Dragy. First I lowered boost to 10 psi on 1st gear, then 20 psi on 2nd gear and then full 23 psi from 3rd and so on.
I'm using a set of Zestino Gredge tires with a 120 treadwear, not the best 1/4 mile solution but at least they get some grip when heated properly.

But my question is: What are the best shift points when launching from a dig? I'm currently using launch control at 5000 RPMs which surprisingly work better than the 3500RPM launch on my car since I'm at 5000 ft over sea level. (it bogs with the 3500 RPM Launch).
I'm shifting at around 6000 RPM on 1st gear, then throwing a 6500 RPM shift on 2nd gear and then shifting at 7000 RPM the rest of the gears...
Am I doing it right? (2.09 60 ft)

Attaching the 12.36 sec video with it's log.

Thanks in advance

It depends on torque in vs torque out. This is variable based on your power output and the gear ratio splits. If you want to calculate your optimal shift points this is a good place to start:

Optimal Shift Point

Calculates the optimal upshift rpm and road speed for each gear of your car to acheive maximum acceleration.

Yeah that's a great tool to calculate the shift points, but my question goes more on the wheel spinning on the 1st couple of gears, specially with boost redux.
I'm shifitng 1st gear at 6500 RPM but I might go a little earlier. More like a personal experience question when not using drag radials.
