I have not personally ran any DPF on tuning. However, in my experience on here and other diesel forums, DPF on tuning (at this point in time) is severely lacking. The additional power created by the tuning seems to create more soot than the factory engine tuning and thereby creating more regen cycles. Which brings with it increased chances of all the terrible regen related issues; clogged DPF, constant regen, fuel dilution, etc, etc.
I do believe that DPF on tuning has a long way to go as far as usability and 'worth' but it will come around eventually, I hope.
Again, this is my opinion and I have no personal experience with the 'street' tuning
