PCV and ECU TPS sync

People with PCV, how are you syncing the TPS? What number are you using. I go in the PCV software and go to calibrate Tps. The idle voltage is right on. But full throttle voltage I get 4.46 on the PCV? But plug sled into digital wrench I get 4.37?

So do I set PCV to 4.37?
Or leave as 4.46?

It seems like to me if I put it as 4.37 then PCV is going to read all the voltages and will give wrong higher map all the way through the throttle position. If I leave it as the calibrated 4.46 the scale is also going to be off.

The ecu converts analog to digital different then the PCV so there getting different values. This seems like a big problem to me? Opinions?
 
Just sync as Pcv states only in manual. Don't worry about what Pcv reads vs dw @wot.
