Still stumped with this 2000 rpm rev limiter. So I replicated the issue while measuring 3 new things:
1. Fuel pump voltage was found to be a constant voltage of ~14.1
2. Fuel pump pressure at the ~2000 rpm range was >=40 psi, it never dropped during the loss of power
3. Map sensor test was good
Also, the wastegate moves freely and it has Autolite plugs that look good, all vacuum lines were replaced... I don't have a spare DI but it looks like the next step or maybe draining the fuel, there is a full tank of gasoline in the tank and it was filled up just over 1.5 years ago.
