3 stage fuel system cleaning?

[jtoddk98]

I wouldn't mess with the cleaning. The higher ups at Ford engineering don't have a recommended cleaning process yet. Current ones are not good for the turbos. My car has 56.5k miles on it, never had an injection cleaning. Best way to keep the valves clean is a heavy foot, Ecoboost like to be run hard.

BTW, in the video, BG points out that a maintenance plan is the best course of action for the GDI engines (and any engine I am sure).  Walnut shell blasting would be the next "safe" choice for intake valve cleaning if the engine already has miles on it.  You could also try a small amount of solvent for each cylinder, agitate with a soft bristle brush, let sit overnight, drain/clean thoroughly.
