Hmm, that is the way I normally run my diffs for RM cars. Yeah, I guess everyone was saying the MM car needed tighter diffs, so I used that as a starting point. I need to rebuild the diff, so when I do I will set it like I normally would. I was told my car was not squaring up fast because the diff was too loose and that it was diffing out. When I tightened it, it seemed better to me. Much better forward drive.
