Yes, I have a full set of NGK 97506 plugs I plan on installing when I install my catless downpipes and stage 1 tune just as preventative maintenance. At 41,000 miles, the original plugs are probably nearing the end of their usable life, but I doubt plugs are causing this issue. Most issues involving plugs I've encountered on BMWs over the years, especially boosted ones, will pop up under boost under WOT conditions.
This only happens when I start the car cold, and back out of the garage before the cold start has a chance to lower the RPM back down to normal.
I do plan on deleting the cold start once I add downpipes and the BM3 tune, so I'll see how that plays into it, but I'll try the MAF cleaner before anything else. It appears to me like it has more to do with the DCT transmission at this point.
