It did seem like in the first few videos, especially from second to third between 55MPH and 60MPH you can clearly see the hesitation in the speedometer. Very bizarre. The last video probably has times in the low 6.0's, which is markedly better than what Scott was putting up earlier. I really hope you can enjoy the car now. Sucks it happened in the first place. I'll also add that changing the octane of gas seems like a very unlikely fix, although the computer hard reset (ECM) may have helped. If you know it won't void your warranty, pull the fuses and check it out to confirm. Better than sitting idly by and complaining about it. GM isn't going to contact you over time, so don't sit on this.
