Does that minni max have the programming to fool the ecu into thinking the dpf is still there? That would be my first guess is the minni max.

Ya it should have that. He called h and s and they said check the fuel filter so he changed it and it went away but now its back and the new filter has only been on for a week or two. What would the fuel filter have to do with the exhaust system?

The fuel filter really has nothing to do with the dpf, except for the doser unit that mounted to the exhaust down pipe,that injects fuel into the exhaust stream where the dpf uses it to burn the ash in the dpf catylst.
Other than that,

Wish I could help more, but I'm thinking the mini max might be the issue.
