I need opinions on a black bear performance tune. Anything I should be worried about? Any tips?

Curious why you made a new thread on this? What was wrong with the info you got in the other one?

Nothing wrong with the info from the last one I just have some people telling me its going to destroy my 4L60E and other people telling me it's fine.

They will tune it however you want. You can keep the shifts stock or several levels firmer.

As I stated in here:

https://www.gmt400.com/threads/1997-chevy-c1500-5-7.62815/

As long as you don't have them modify your torque management at all your 4L60E should be fine. If you're really paranoid you can leave the shift firmness stock as well (I probably would, IMO the stock shifts are fine). If you leave those two settings alone then they're not messing with anything on the transmission side of the tune, it'll behave just like it already does.
