You should really dig slightly deeper before judging things.
The "E" and "F" engines were high altitude versions of the "A" engine, equipped with a three-speed two-stage intercooled supercharger.
While the rated altitude of the "A" engine is 5.000m, the "E" and "F" have a rated altitude of 9.600m.
Particularly the "F" engine was equipped with an additional high altitude booster (GM-1) and could deliver a WEP of max. 2.050hp.
You must note two facts:
Bottom line: If you absolutely don't know what you're doing, the D-13 isn't the right aircraft for that task.
However it is superior to the D-9 at high altitudes, and that's where the battles took place at the time the D-13 was developed.

Particularly the "F" engine was equipped with an additional high altitude booster (GM-1) and could deliver a WEP of max. 2.050hp.
You must note two facts:
- The WEP of the full equipped (MW-50) "A" engine is higher (2.100hp) than that of the "F" engine (2.050hp), but at lower alts.
- In order to utilize the full "F"'s performance, you have to switch off and back on WEP at an altitude of above 9.000m.
Below 9.000m the WEP key (default: W key) enables MW-50, above that altitude it enables GM-1, the high altitude booster.
Please consider the IL-2 Aircraft Guide for details, the Ta-152H-1 is a pretty well comparable reference.
Bottom line: If you absolutely don't know what you're doing, the D-13 isn't the right aircraft for that task.
