The 5.3 GDI L83 in my 2014 Silverado has a variable displacement oil pump and per GM requires a high PSI bypass oil filter:

The use of a replacement oil filter with an internal bypass valve opening pressure specifications of 15 PSI (100 kPa) or less, allows debris to circulate in the engine causing damage to bearings and other tight tolerances areas, which may result in premature engine failure.
The oil pressure was increased to accommodate these tighter tolerances. As a result, the oil filter specifications of the production oil filter and the service oil filter were also improved to meet the new engine requirements.
Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.
Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters.
Important: The PF64 and PF63, which is commonly confused by many in the automobile service industry as an ACDelco® PF48 and/or PF48E , because both oil filters have the same appearance and oil can size. However these oil filters are not the same and have different internal bypass valve opening pressure specifications (PF48/PF48E = 15 PSI (100 kPa), PF64/PF63E = 22 PSI (150 kPa).
Note: Any aftermarket filter must also have an internal bypass valve opening pressure specification, element integrity, filtration performance, media particle trap specification and burst strength that is equivalent to the ACDelco PF64/PF63E filters.
The following filters are recommended for my truck by the filter manufacturer with their bypass setting listed:
Wix 50745 - 12-15 PSI
Fram PH10575 - 9-15 PSI
Mobil 1 M1212A - unknown bypass rating
Purolator L22500 - 22 PSI
Bosch 3502 - 15.5 PSI
Now, if you take the Fram PH10575 and cross this filter into the Wix website it gives you Wix 57502 and magically the 57502 has a 22 PSI bypass but is NOT the recommended Wix filter for my truck. Crossing the Purolator L22500 yields the Wix 57502 as well. Fram seems to point at the PH10575 no matter what cross you try.
GM claims you need 15 PSI bypass minimum and the GM filter even runs higher at 22 PSI.
What filter would you run and why?
Why would GM spec the PF63E at 22 PSI but then allow replacement filters to be 15 PSI?
