Found it still lying on the workbench...

Nah, haven't been able to find the time to put it in and frankly, I am still a little (lot) worried about changing diffs for the first time.
There is a last round of TimeAttack on the 25th september, but a dyno day on the 10th of september, so I need to try squeeze it in between 10 and 25 sept...
I did encounter some inside wheel spin at one point, but this large turbo spins a bit later, so I have less one-sided wheel spins out of the corner then before.
I don't drag race anymore before the diff is in OTOH as my slicks are getting worn on one wheel only, noticeably!
