I own a 2004 C5 Corvette and a 2004 4.8L Silverado.
On my 2004 C5, I've been able to adjust the "desired pedal area" (accelerator pedal position vs kpa) table to make it more responsive. By contrast, if I try to adjust this table on my 2004 Silverado, the ECU flips out and goes into reduced power mode.
Here's my C5's tables (daily driven this way):

Here's my Silverado's tables (stock values, the only values that seem to work):

As you can see, the C5 tables just come in a little sooner to make less pedal necessary to get the TB open. Nothing massive, just enough to make it not feel like a dog.
Can someone help me with this? I'd like to take some of the delay out of the silverado table to make it more responsive.
edit: I forgot to upload the C5 and silverado files. These files correspond to the above table screen shots.
