I had mine remapped with the EGR Delete and she absolutely flew.....but if I didn't give her a good thrashing and only did a few short trips I would then have to start a regeneration which meant driving I didn't really need to do.
I was just going to gut the DPF but I decided to get rid of it and get a straight through pipe. Once I had the DPF delete mapped into it it felt like a new car yet again.
Plenty of threads started in this section recently with regards to the DPF and mapping.
