What have you done with the Ta-152C?
Ta-152C wing area corrected from Fw 190D-9 values (~1.2m²) -> slightly improved turn performance
It climbs worse and is a lot slower now. Pretty useless...
€dit: OK, doesn't seem to be that much off:
It's too slow at high altitudes at least. And the Chart is for Sondernotleistung.
Here's the max speeds for Kampfleistung and MW-50. So it's quite OK down low (oh yes, it was too fast), but at altitude, it's not.
