There aren't any Hydraflash library calibrations specifically for eliminating backpressure valve deleted vehicles. If the check engine light is on just because it's unhappy about the backpressure valve solenoid being unplugged, places like RiffRaff Diesel sell a plug-and-play resistor that fools the diagnostic routine into thinking the valve is still there.
Deleting the valve has no impact on performance or tuning anyway.
