It's not slipping, but the logs are proprietary for now which is why I described it as a teaser.

Very pleased with it thus far.

Awesome, once you guys get this tuned, verified, and a licensed distributor, I will be making a purchase to go along with my gcs.

How is this a tease? It's a dynojet, no load... Multiple people have done this on a stock trans on a dyno. Show it launching or shifting at 30+psi on the street.

No load is.. well, wrong, but actually overall I'm with you. 30 psi at the street/track sounds good.

There is a process for break-in and calibration at least during development/etc. The above vid is part of that process. In the vid the car was about 675 whp.

Ok, real load not no load. I figured you guys were past break-in period, but good to know things are moving. Having an auto myself I'm really looking forward to results.

Chris - with the upcoming advances to the 6AT on this platform, it is only fitting that you and I swap transmissions. I'll do you the favor and take your outdated 6MT off your hands so you can take my babied 6AT!

exciting moment for 6at guys.... but kinda sounds weird not hearing the pops and bangs like the DCT between the shifts, i wonder if there is a way to add that in with the quicker shifts,,
