Chip shock

I got my Peugeot 406 2.2 diesel coupe ECU remapped in October. It didn’t run very well at all until I cleaned all filters. Now she will run 100% for about 3 weeks then the filters will clog up again. What will I do? Will Millers Power Plus solve my problem?

Further correspondence established that the Diesel Particulate Filter
was getting blocked, probably because the engine ECU remap had not accounted for the engine cycle needed to regenerate the filter.
