Looks like misfires were the transmission
It's been almost 9 months since it first starting misfiring at high RPMs. We replaced the lifters, still there. Then Porsche reckoned it might be an unbalanced driver shaft but weren't sure. Then the tiptronic failed because of a bearing failure and it was replaced. I drove the car today and did 6.7k rpms in 2nd and 3rd several times and no check engine light. It might have been the transmission starting to fail all along.
