DPF replacement

Before any tuning, I would recommend you check the following things:

1.) EGR differential pressure sensor - can cause issues if tubes are clogged or sensor is bad
2.) Exhaust back pressure sensor - when bad can cause turbo chuffing and frequent regens
3.) EGR valve - leaks, etc.
4.) EGR cooler - when this leaks it can cause total failure of multiple components.
5.) IMAP sensor - clean and/or replace
6.) After-treatment injector - clean and/or replace - can easily cause frequent regens and soot build up.

After checking all these, do a forced regen with INSITE and see what your DPF differential pressure is reading after. Should be under 1.00. If any higher you have other problems that a tune won't really solve.
