If you
can maintain constant power (turbo charging), you get better and
better performance with altitude.

The TAS will increase, but say you want to hold a specific angle of
attack and its attendant IAS (maybe for range), you will need more power
to do that as you get higher.


This in not true. You will need the same power for the same IAS
regardless of altitude.


Don't listen to me. I was wrong. Same IAS at altitude requires more power.
