91 octane is really slowing you down. Your truck is designed for 89 octane and a slower burning 91 is not helping your cause at all.

Second, your truck is new. Give it a few thousand miles and you will get faster.

Couldn't hurt to recalibrate your peddle like you said. I've noticed it makes a difference every now and then.
