Long story short -- Car has been tuned by Lund a few months ago and I haven't had any issues other than trying to do dyno pulls. Earlier this week I went WOT and back down to cruising speeds. As I tried to hit 6th gear, the car revved up about 500 RPMs and I quickly put it in neutral out of a panic. I just drove down the interstate (only 2 exits anyway) in 5th. Figured it was just a one-time issue.
Today it happened again after going WOT and back down to cruising speeds. Tried going from 5th to 6th and, again, the car revved up about 500 RPMs and dropped down after a second. It revs up about 500 RPMs even when going from 5th to neutral.
I've brought it up to a few people and some suggested it's rev hang and built into the tune, others think it's possibly a sensor and has something to do with the heaters and heat. I've gotten the car much hotter than this on both track days so I'm not quite sure personally.
I took a video and sent some logs off to Lund and waiting to hear back. Really curious to hear some feedback from anyone who may have had a similar issue in the past. Here's a video if anyone's interested:

TL;DR Car is revving in between gear changes, including neutral. Not sure if it's tune-related or something else.
