I have a 2019 440i Gran coupe with the Resonators removed, and axle back Remus exhaust installed. I DO NOT have the MPPSK Exhaust.

When I flash my car with the BM3 MPPK tune, the car feels more “sluggish”, less quicker, and the fuel throttle response sometimes gets “jumpy” - hard to explain but it’s as if I’m letting on/off the gas 10 times in a second.

The second I flash back to stock (non MPPK) the car feels amazing.

Does not having the MPPK exhaust cause the tune to not “fit” the car correctly?
