Good.   It took me a long time and lots of failures to find a recipe for massive stars that works at least some of the time!  While you are of course welcome to start over without using the results of my "blood, sweat, and tears", I think you will make faster progress by doing incremental changes to the relevant inlist from the test_suite.  However, don't treat it as the immutable final answer either!  There are undoubtedly things in there that are not really doing anything useful -- leftovers from my many failed experiments.  And there are also surely things that could be done differently that would improve performance and accuracy.  So I'd encourage you to spend some time to understand the things in that inlist and try making changes to them.

Cheers,
Bill
