Hello guys,

I have a question about stock 1.9 tdi voltage pump map axis quantity.
As you can see a standard AFN 110 HP engine has this voltage table and see this ends with 51mg. Attached picture

The 50mg and 51mg column seems as 51mg has more voltages than 1mg difference should be. It seems its the maximum voltage what the fuel pump could handle. (I know maybe 4,5 volts till 4,75 - 4,8 V could be the maximal limit)
I wonderring whether is it really 51mg? Or something like 53 or 55mg? Some vp guide said 57mg fuel is the max of the stock pump.

What you think about guys?

Thank you
