TMC2208 Drivers on 1.5XT+

We had our RAMPS board go out and we did an overhaul to RAMPS 1.6+ with TMC2208 drivers for everything but E0 and E1.
I think we changed everything in Marlin we needed to (including config_adv for TMC2208) and the printer seems to act normal for the most part.
The issue we are running into is some layer shifting (as early as layer 2) in the X axis. We thought we would see this in the Y with the large bed but it seems to be isolated to the X for some reason.

Has anyone tried installing TMC2208 drivers on their gMax?
What vRefs did you use for your axis's?
Did you need to change anything else in the firmware?

Thanks!

Hey everyone, just wanted to shoot out an update in case anyone wonders upon this in the future.
We were able to get the printer up and running. vrefs for X and Y are both at 1.1v and the Z we had to bump to 1.4v.
We beefed up the cooling fan on the control board as well and everything seems happy for now! Amazing how quiet this giant printer can be!
