This was the point of the LT4 supercharger. It amazes me that the LT4 has a 10:1 AF ratio but that is important to the choices made included the smaller blower.
Little read about the motor.

As someone daily driving a car with a LT4 I have to say I have never felt a car this strong down low. My 670+ HP Mustang with a Centrifugal pulled crazy up high but was lazy down low. My ZL1 was strong down low but you could still feel the motor come "into the boost". High boost turbo cars were the worse. The LT4 feels like a large NA motor and that was the point.
That being said the design is built to a certain limit. In the Z06 world you get much over 800 hp at the crank the LT4 blower comes off and a Procharger or turbos come on. No one and I mean no one is running a 2.3. (And there are kits that fit the car.) A few tried them but the power difference was so small it was not worth the money. Even the Callaway cars don't make much power over a modded stock blower car. The big thing is the cooling brick design issues that caused overheating when running WOT for extended times under high heat conditions. This was resolved in the 2017 model cars with the new taller lid and brick layout.
