Yes, a bad map will cause problems because they delete every single fault code out of the ECU to get rid of DPF faults, the only problem is that you can't diagnose it when something goes wrong.
If you get some readings of MAF on idle, and also MAF and boost pressure on full boost then I'll try and point you in the right direction.
