Hi i have a 2013 passat with the vr6 engine and i want to put in a mk5 r32 downpipe(sport cat version) into the car for the sound and torque but as i know you need to tune the car after that.
I could not find a off the shelf tune for this so i was told to come here for a custom tune i guess. Does anyone know what i need to do this? Do i use my existing ecu or do i need to get a different one? If anyone can do this for me as well, please reach out to me asap.
