The past few months I've notice my truck has a vibration at idle. (I know it's a diesel), but, it use to idle as smooth as a gas motor. Now, it seems to gotten worse over the past few months. Maybe I'll try to get a video of a cup of water in the cup holder so I can give a better explanation on this vibration.

What to check?

Check the motor mounts, check the dampner for tightness or signs of failure, check balance rates to see if maybe you don't have a couple injectors that could be failing.

Try switching to your stock tune and see if it makes any difference.

Engine sounds good, balance rates are all in check. I'm going to try to change the tune and see what I come up with.
