New 2019 Tacoma owner - Question with truck

Hello everyone I just picked up a new 2019 Tacoma for a work truck. Already added bilsteins/ome 887’s, 1.5” block in rear, and pro grill. I really like the truck so far. There is one thing that is driving me nuts though. From day one I feel like there is a slight vibration and bogging feel in 6th gear at low rpms. I can’t really explain it but if feels like the truck is being pulled back slightly giving it a vibration like a wheel would be out of balance.

Once I did the lift it became more apparent. My wife even commented as if she thought a wheel was coming off.

Anyone have this on their new Tacoma’s?

 

That’s new to me, bud. But welcome. Hopefully someone can point you in the right direction.
