I sold my RS4 awhile back so I don't have a dog in the fight, I do miss my car tho, probably useless but who knows.

I am almost tempted to give it a try, might not be a bad idea for the interval between cleans. Although I am nervous about fouling my injectors.

doubtful. i have tried even stuff like the CRC direct injection spray. i might as well have been spraying water, hopes, and dreams.

On this topic, is anyone else hear about using BG for carbon cleaning over walnut shells?

Ive heard it's effective using the same methodology only... I.e. it works great when you pull the manifold and soak the valves. Personally, if you have the means, I'd still go with walnut/baking soda media blasting, but it works great with someone without a blaster. I haven't heard of anything yet that works by adding it to a running engine.
