Fresh back from the drive and everything is back to normal. The hesitation is completely gone and replaced by.... still a lacking amount of boost
However, I don't believe modifying something that isn't working smoothly.
So, to those that are getting up there in mileage, which I know isn't many of you, don't forget that intake cleaning around 30k - 40k miles.
Thanks again to ayao and flzrider for the suggestions. That definitely helped me get things fixed a lot quicker.
