Hello everyone!

I'm thinking on remove dpf om mine F11, 525D, but i have a serious question, and I wonder if anyone can clarify me.

After remove DPF, and install a pipe down, it is needed to change MAP.
As I haven't find out yet where to change it, i will buy this job ,but:

-->After that if I made a ECU firmware update, using ista+, all parameters will be lost, and need to code MAP again, correct?

Once again kind regards and very thanks for the information.

Second question,
is here anyone from oporto Portugal, that recommends someone for these job?

In past I have flashed e46, now will be F11 :)

Firstly u must to remove all services about DPF.
Second u must turn off your DPF on Soft.
If u upload your flash file i will turn off your DPF.
