This is not a Melling pump, this is our own Speedway oil pump. The Melling pump with high quality gears and casting material is the Melling Select pump part number 57710550.

No the issue is that with 20w50 oil at cold temperatures the bypass in the pump is not able to bypass enough oil to get the oil pressure under control. The thick oil is the reason for the high cold oil pressure. The pressure seen at 4000 to 6000 RPM at operating temperature is the true pressure that the oil pump is set at with the current spring. With 20w50 oil you always want to warm the engine up very well before it is revved above 3000 RPM.
