2.7 Strange rev spike at low speeds

[Jaolered]

Hey all,

Currently sitting at around 5k miles on my 2021 Silverado with the 2.7T. Engine has been great overall, but there is a really annoying and noticable behavior at low speeds. When accelerating from 0mph, not matter how soft I accelerate, the tachometer will jump from 1500 rpm to 2500 in a "spike" method. It's a noticable engine growl and doesn't match the acceleration at all. Is this normal for the 2.7/8 speed? 

 

This isn't a gradual rev when accelerating, which is on obviously normal. On engine sound, it jumps from 25% to 100% to 25% again in just a second. Thinking about driving another 2.7 when this goes in for an oil change to compare.
