Car Idle Issue/Shifting Issue

When I am in D and not DS my car is still shifting similar to DS would. It would shift around 2-2500K but will shoot up about 400-500K. Any idea why?

If you have a Bav Tech tool, you can reset the transmission adaption values. That might smooth things out,

Is it worth it to buy a bav tech tool? I saw them being sold pretty cheaply.

I was having a misfire under cylinder 3 and 6 when running Cobb... do you think this could be the injectors?
