I usually have a ballbearing 70 on my 249ci stroker engine with 75lb injectors and ME-R.
The turbo got damaged, and now the stock turbo is back on.
What settings should I be changing to get the car running a bit better for now?

You'll have to dial the thumbwheel down to lean it out. You may have to go all way down to 1. You might also have to lean out the fuel in the 4000rpm area, but I would just do the thumbwheel for now and see how it goes. It is possible that it won't go lean enough for a stock turbo.

Results are in!
Car wouldn't rev much over 4400 rpm due to back pressure, turbo put out 16-17 psi max. Ran a 12.21 at 111mph. Not bad considering!
