My engine is not YET boosted, but soon will be. So to honestly answer your question, no. But low speed preignition is not the ONLY issue that the GF-6 rated oils have been formulated to address. See the chart below.
All engines suffer from wear throughout the duration of their usable life, which IS the "....problem [that I do] have", and engine oil is the only protection from excessive forms of it. I am of the opinion that the best quality oil that I can get should be running through any high performance engine such as the FA20/4U-GSE. And it's even more important when it's boosted. If this were an economy engine such as is in my non-vvt V6 Solara, I would not bother with the highest quality oil I can find as it would make absolutely no improvements to the operability or reliability of that engine.
I'm perfectly willing to try new technologies as long as they are proven to work. The new GF-6 formulation definitely won't be WORSE than the existing GF-5 at protecting engines. Otherwise, why would millions of dollars be spent on the research and development?
But if you're happy with the oil you're currently running, keep running it. Nobody's going to force you to do something you don't want to do.
