Default Big converter loss

I recently swapped out my m6 for a built 60e and a Yank ss4000. I went to the dyno the other day to do some tuning and to get a comparison with the big stall. Here are my new numbers and you can see that there is a huge loss with the unlocked converter. She runs like a bat out of hell now though. There is nothing like big power and a big stall.

A better comparison is getting the graph in MPH instead of RPM.
