DAS for the duo-valve

DAS owners,
Are there any adaption/calibration options for the Duo-valve or manual A/C thermostat knobs in your car? I've noticed, with equal settings left vs. right, a slight temperature difference left vs. right -- in both heating and cooling (the right side is always a few degrees colder and it's noticeable to the touch).

I'm wondering if the valve has gone bad on one side, or if the valve and/or knobs just need adaption/calibration. I'm also wondering if I replace the valve will I need to adapt/calibrate it as a matter of course.

Thanks in Advance!

Can't give you a direct answer, but have you considered the cold air motor is on the right side behind the glove compartment? This means the left side is always 'last' to get the air. (in LHD vehicles)
