E90 3-Series Carbon Build Up N54 N55

We recently started performing Carbon or Walnut Blasting.  This is a process used on Direct Injected vehicles to clean the carbon build up off of the intake valves.  Carbon build up can lead to rough idle, misfire and poor performance issues.  This customer commented that his vehicle felt as it did when it was brand new.  ImageImageImage
