Yeah that one was pretty close. The video actually exposed the issues. In the first pass we could hear 3 slight misses in the top of second gear. I think the MAF was the primary cause, however decided to inspect the DISA. I was pretty shocked.

Took her to the top a couple times in second gear and no missing. They were definitely due, there was a moderate power gain.
