“The Lt4 1.7L roots style blower is strong in the low to mid rpms but falls flat at higher rpm.”

“ To sum it up - underwhelming boring feeling acceleration”

Perception is, of course, a subjective experience. Being a rider of a 200 hp bike capable of 9 second quarter miles, I have a sense of strong acceleration. While being nowhere near as quick as my bike, I certainly wouldn’t call my ZL1 underwhelming or boring.
Perhaps I got a strong example or yours was a bit off, but mine pulls harder and harder right up to redline.
