X6M decreased power
Hey all,
I have owned my 2011 x6m for 45,000 miles now. I have a meisterschaft gtc exhaust.
It's been a while since I last pushed my car to maximum throttle and recently I noticed that the car is under performing. It's not pushing like how it used to.
Could there be build-ups in the engine, clogs or anything that needs to be cleaned out for the car the perform the way it used to?
Thanks in advance!
