Just need an idea of what to use for a setting for Sunlu basic black PLA. I spent 3 hours online trying to find answers and working with AI to make a setting. After getting the settings listed by AI, I found out it was wrong b/c some of the things it said could not even be entered into a profile b/c the numbers were below what Bambu Studio allows as default! I want to do a torture test but have no idea where to find proper edits to the filament profile once I get a printout. Does anyone have a working Sunlu PLA Basic black filament profile or know how to set it? I have seen online people say the generic PLA in Bambu Studio is great and others say its is not?! 
Just use the Bambu Basic PLA setting or the generic PLA setting. They’re very similar. It will work fine.
Thanks - much appreciated. Will give it a shot.
From my experience, the BamBu Basic PLA setting will work fine. But sometimes using the generic PLA can produce better result.
Thanks. I have come to the idea it has to be a defective roll of filament. The twin to this one I ordered is working perfect with default settings. Elegoo has been working with me on this as well.
Are you sure the ‘defective’ roll is dry? Doesn’t matter if was a new roll, still vacuum sealed. Better to dry it well (overnight in AMS2Pro) or use an external dryer box. You’d be surprised how many allegedly dry rolls will not print cleanly until you give them a thorough drying cycle. I run almost exclusively Sunlu filament with nearly zero issues. Started with PLA as I transitioned from a Prusa to the P2S, but now 100% of what I buy is Sunlu PETG. There are some Sunlu profiles out there, but mostly I use the generic PETG profile with a few personal tweaks. I think the generic PLA profile will be just fine to get you started, but below you can find the Sunlu profile I downloaded from somewhere. Its in JSON format but the key parameters are easily readable.
Hope this is helpful.

Oh no…just noticed at the start of this thread I said Sunlu! It is Elegoo that was giving problems. Sorry about this to everyone.
Thank you for all of of you help.
And Elegoo also agrees it is defective. I sent them pictures and videos of various failed prints and have had a lot of back and forth withem. Good PR dept. They are the ones who suggested it is defective and asked me to check the other rolls I got in same bacth so they coud re-imbusre if they also turned out this way.
