Did you clear the codes and reset the tables? Was the old filter bad?
It could be the pressure sensor. When the DPF filter is replaced there is a service function in the scan tool. This resets the DPF adaptive learning tables. The other part is when a new one is installed they want you to perform a manual stationary regeneration. Installing a new DPF without resetting the tables with a scan tool can throw off the system.
