Yes he did have to do some modifications to remove the re-genreation cycles and DPF related entries in the ECU. He's done a few and works very closely with MegaSpeed on that part so I wasn't worried. I haven't had any problems with SES lights or malfunctions. All is good.
The Urea injection is still active but we are working on getting rid of that. I don't really care much myself as it's a normal part of the car but he is working on a way to remove that as it isn't necessary anymore now that there is no DPF.
Let me know if you have any other questions!
