I noticed my car have waaaaay less burbles and pops. How I know this, I used to have it in sport individual mode with engine and trans in sport +. I used to shift from 1st to 2nd at about 5k RPM and it would pop, same thing downshifting. Took car in for ticket that I received of "loud exhaust" to deem the car was insteed stock. Received car back and what do I realize, no more pops when shifting, no pops downshifting.
Solution: flashed to stock with bootmod3. Now it's back to how it was prior to taking it in. It sucks that Bmw is doing this, but I found a way to fix it.
