The whirring is still there but I guess that doesn't mean anything, I popped the seat and cover off and took a video for you guys while the car is idling. You can hear the speed of the pump drop a few times during the video, this corresponds to a small drop in engine rpm, is this normal?

I should also mention the pump has no problem supporting my PTE 880 injectors at 80%+ duty cycle, the car is just very hard to start when cold and the idle is a little rough, I've always attributed that to my HKS 272 cams though.
