Check the age on your plugs. The stock intervals are 37K but they really should be replaced about twice as often to maintain optimal performance. They make a serious difference, especially at lower RPMs.

The M5 is my dad's - but I drive it more than he does!

Sold Sept '16. It was an amazing 7 years.
