How will your tranny tune for towing 4-5k?

It is the same tune you have in your 335d, except X5d shifts points in D and S remain unchanged from OEM. You can decide if that is of benefit. From your perspective, what is the benefit of the xHP stage 1 for towing?
At OEM power levels, I think the OEM TCU tune is decent. I do like to tweak the shift points at low accelerator pedal percentage for improved economy.
