Stuttering WOT

After reading this post, I'm really thinking I need to change my spark plugs, because my car doesn't stutter at WOT, but it stutters at freeway cruising speeds every now and then. It almost feels like fuel cut but I'm not sure, I've never felt anything like it in any of my other cars.

Not really. What fixed it is it got warmer. I think the boost was spiking, causing the ungodly thud sound.. That, and maybe the v201 map. The FPR swap helped a little initially, but then it resurfaced. If you're in warm weather, I have no idea what to tell you. Log it, look for a lean A/F, watch the boost. The v400 peaks at 29, so it already sounds ridiculously high, but it shouldn't be more than that. But as for a specific cause, if it gets cold again and it starts up, then the cold messing with the A/F will have to be the gremlin. I pound on the car daily, and since it's been above 45, all is good. Let me know if you find something different.
