Issues after SMF install

So I finished the install yesterday and took it for a ride. It seemed fine.
I took it to work this morning and then to class.

On my way to class, I noticed a vibration sitting at stop lights in neutral with my foot OFF the clutch. I can see the hood vibrate and the door mirrors (like a Harley at idle)
It does not change when I depress the clutch pedal.

Then while trying to find a spot in the parking lot, I noticed it is very noisy (sounds like grinding) in first gear. I do not have the inspection plate installed for the time being.

What should I look at?

Thanks

Sounds like the typical SMF symptoms to me.

Garrett you think you can deal with it? I may have a DMF on the way out and I'm trying to weigh options/opinions on the SMF

So the 'growling' is normal to the SMF.
I'm not sure the vibration is. I popped the hood with it running and the engine is definitely moving about more than I would imagine.
Perhaps my engine mounts are just that bad and the semi-functioning DMF hid the issue?
I think I'll Diesel Purge it this week.

The growling is normal, commonly referred to as gear rollover. I too noticed a little more vibration after my SMF swap. I over filled the transmission by a quart and increased the idle speed to about 750-800rpm to try and help smooth it out.

I remeber a while back someone had a bad vibration after converting to smf and it ended up they got the wrong flywheel ( turbo one instead of NA or vise versa) and the turbo one was something like 3 or 5 pounds heavier.
