Is it possible to remap the exhaust back pressure

[ndwgolf]

I have a new 2019 E53 Coupe. I recently installed a new titanium CATBACK exhaust which has messed with the ECU that operates the turbos ................basically if I try to floor it the turbos stop working and the car goes into limp mode (I'm assuming this is caused by the open ended exhaust pipe not given the ECU the correct back pressure. So my question is this. Is it possible to change the expected back pressure lets say it supposed to show 6 psi back to 1 psi
Thanks in advance

Possibly , but not sure if you have been following OP's progress with hand built exhaust. My money is on the Exhaust/sensors.

Is it possible to manipulate them with a retune?

I have no idea but I am sure your car is not the first to have had such an exhaust made for it . There must be someone out there who has similar. best of luck.

There are many CLS53 in Thailand that have had the same exhaust installed without Issues.
After reinstalling the original Benz exhaust the problem went away which tells me it’s something to do with the back pressure……. But I’m a roughneck so really don’t have a clue
