So, after a good bit of diagnostics via data log on Tom's part, he was able to resolve the issue. It turns out that it was an issue related to the VCT. He can explain in more detail I'm sure. After adjusting the VCT, the issue appears to be negligible at best. Now to fix this incessant rattling coming from the exhaust!
Many thanks to Tom for his patience with me and my car. Highly suggest him for tuning.
