I wouldn't say that blaming the tune is mis-guided. My tuner's APR rep was the first to suggest that the tune toasted an already-marginal WG, and the legendary
@Diggs24 himself first suggested it might be a tune issue (before I flashed back to stock and confirmed hardware issue), and his current theory (regarding the front end lag) is that it's the nature of the beast with an 87 octane tune (pulling timing at sudden WOT). Given how jarring the full-second throttle lag is, I'm not entirely convinced of that theory, and it doesn't explain the rattle. Regardless, all of this narrative is documented in this (now lengthy) thread.
Yes, I flashed back to stock a few weeks ago. Page 2, post #18. That's how I finally got the P0299 code and confirmed WG or DV was bad.
DV was likely bad, too. Page 4, post #54.
I do have a log here. A few of them:
Pre WG replacement data - Page 3, Post #33
Post WG replacement data - Page 4, post #48
I did take a video before I replaced WGA - Page 1, Post #1. Though that's outdated now since WGA has been replaced and the lag has been reduced to a consistent second or so.
It's all in this thread, over which I don't think I blindly blame the tune. Rather, I'm trying hard to diagnose a gremlin that has been persistent since day 1 after my tune (so naturally, the topic of the tune is a common one in this thread and the timing is suspect). I'm also trying to do this in a well-documented manner that may help someone who experiences the same frustrations as I.
