Well finally got the truck back together and was looking forward to the track this weekend but have hit a snag. I attached a log, my tune and config.
I am launching in 4x4 and it leaves hard and as soon as it get to the 1-2 shift it just falls flat on it's face. At first I thought I was hitting a rev limiter so I raised that to 6600 so that is no longer the issue. I looked over my log and see that the "Trans Slip RPM" was up to 2500 RPM at 30MPH when WOT and that when it shut down on me.
I had a local shop build the motor and due the tuning but he is not familiar with the new A6's and I am completely lost. Can anyone take a look at my log and tune and see if they can offer some assistance. It looks like I need to up the pressure so the transmission holds better and doesn't slip as much but I don't know where to start in doing that.

If you need any more info or more logs let me know. I'm pretty furstrated. Tomorrow is the last track day for the year up here and I don't think I will be able to make a full pass with all the new goodies on the truck.
The "trans slip" log was taken at the track. It starts at frame 6080.
The other log was from a back road where I just got on it half throttle and it behaved much better.
Thanks for any advice. I really don't want to have to pay for another tune. Not even sure who else I would trust up here.
