Are you running an electric oil pressure gauge?
I'd start with a simple thing like the gauge and or sending unit if it's an elec gauge. I've had faulty sending units that read low press JMOHO

I don't know the oil pressure at dyno. I am running an electric sending unit. I'm taking the oil pressure readings off my laptop from the ECU. My gauge is also, driven by the Mast ECU.

I was trying to say that I doubt that the bell housing could be so misaligned that you get a bad vibration, yet have the vibration compeletely disappear when you depress the clutch with the car moving. The input shaft is still inserted into the pilot bushing and is still hypothetically being whipped around if the bellhousing is misaligned. Again, I'd look at the engine and the flywheel/pressure plate. Was the pressure plate new and zero balanced?

Ok I understand what you mean now. The flywheel is the Ram aluminum and the GM LS7 clutch. The parts here:

I'll see if I can get a gauge to check it. I'm running the vaporworx setup but there could be something wrong with the pump I guess.

So did you drop the pan tonight?

Hey Doug, it was good catching up with you today as well. The o ring is not going to be a "quick" fix sadly. I got under the car tonight and I need to pull the rack and either lifting the motor and/or removing the transmission. So its going to be a lot more work to get at the pickup. I probably need to pull the trans to check the clutch anyways so I may go that route assuming it's not some weird fuel pressure thing that Todd is suggesting.
Thanks everyone for the help. The advice is much appreciated.
