Is this a blow-off valve? While DV+ and OEM are both diverter valves.

Difference being a blow-off valves vent to atmosphere and a diverter valve recirculates the vented air back into the system.

Blow-off valves, in theory, will increase lag and make the car run richer during venting. Possibly requiring a custom tune.
