Unrelated (evap leak and turbo wastegate solenoid "A")
first thing I did was check the codes.
I did not get the light again after a short drive in down to the store.
i had to rev it a little higher on a 45 minute trip since the car is really slow now. Perhaps the turbo wastegate solenoid is the next thing I should look at?

Even with the turbo charger code, it had a little boost, and wasnt that slow. Now it feels slower than my 2010 LT with 225k. Even at 3k rpm it's very slow. Yeah no balls I guess.

Why does insufficient oil pressure form in the turbine?
The turbine oil supply system is entirely dependent on the engine oil supply system. The turbine does not fail on its own; it only fails in the event of other problems with the engine. That is why, if there is insufficient oil pressure in the turbine, then the operation of the entire oil supply system should be studied.
Possible causes of low oil pressure:
The engine oil filter is clogged and needs to be replaced according to the regulations.
The engine is filled with oil of the wrong viscosity.
The oil has already exhausted its service life and requires replacement.
The oil channels through which oil moves in the engine are clogged.
Engine wear, chips and other dirt enter the system, which prevents the movement of oil.
Problems with the high pressure oil supply pipe to the turbine.
After a comprehensive engine diagnostic is completed, a professional will be able to tell why insufficient oil pressure has formed inside the turbine. The most optimal way to solve the problem will also be proposed.
What are the consequences of insufficient oil pressure in the turbine?
During operation, the turbine rotates at a very high speed, this is necessary in order to create the necessary air pressure in the intake manifold. The higher the engine speed, the more gases are released into the exhaust manifold, the faster the first “snail” rotates and the faster the second one rotates. At the same time, as the speed increases, the oil pressure in the turbine also increases, because more of it is needed.
If at high speeds an insufficient amount of oil is supplied inside the turbine, it is quickly produced, and as a result, the shaft may jam. A sudden stop of the turbine during operation can destroy the blades and even the housing of the turbine itself, so expensive repairs or even replacement of the entire assembly will be required. It is necessary to constantly monitor the oil pressure in the turbine and engine; if problems arise, solve them immediately; further operation will lead to serious malfunctions.
