PSAT 8/9 to SAT scores

For those of you done with the SAT, how much did you improve your score from the PSAT 8/9 (if you took it) to the SAT.

S19 scored a 1240 on PSAT 8/9 and as a junior scored a 1570 on SAT.

What score could I be expected to get with regular preparation since I got a 1310 on the PSAT 8/9?
