Lol this ain’t my first M car brotha I understand what your saying but no one would think to replace spark plugs after 3k miles on the car (tuner agreed no need just gap them 0.018) then misfired replaced all of them still had the issue. They tried Re-flashing it 5 times and fucked the Dme then finally figured out it was a lot bigger of issue then coils or spark plugs. Lol but yea never heard of running quality injector cleaner... especially with brand new car. But I agree @m6beast some cars agree with tunes and some don’t. Hopefully it’s not the car but we’ll see if the next tune does it tho..
