If you are getting wheel spin, might try to change a less aggressive DCT mode to get a smoother gear change - say S3 or something like that?

I believe those 3 spikes is the surge of power he gets from MAX boost at the top of the gear change. Once he shifts gears the boost drops back down.

You can't even see the shifts on my chart below because I'm only running 5.5 psi. Drew even gets a surge going from 4th to 5th gear!
