I did a '04 5.3 /auto setup in a 1957 p/u .All stock & there seems to be a hesitation if you try to accelerate slowly but if you stomp it there is good response. Thanks for any help !
All the pedal & tach module are out of the donor tck .

Several things. Is it tuned?

Log AFR at part throttle (with a wideband)
Is it entering closed loop?
Scan for any DTC

Jim in PA has done considerable research on the topic... Try a search.
There are table adjustments that can be made.. USE CARE doing them..
W/ EFILIVE, you have to have the Flashscan hooked to the laptop to see the table[s].
