195bhp how much more would you gain if you removed the dpf.
Figures vary and people quote anything from 10-25 extra bhp
My plan is to run the car as it is and monitor the DPF levels; its still doing its job nicely (hugs a very large tree) and my motorway journeys do a grand job of burning off the soot it collects
If and when it fails I will replace it but until then its staying put
