ecm engine control module
tcm transmission control module
fpcm fuel pump control module
bcm body control module
etc
Your 5.3L ecm IS the same used by a 6.0L, it's just a different version of the program.
Depending on the tuner's mood, they might
edit your engine program file
overwrite yours with an OE 6.0L engine program
splice a new file using both yours and a 6.0L engine program - depending on which set of (IDENTICAL) injectors you decide to use
If a non-OE type cam is used, you'll likely pay the tuner more because they'll need to use additional talent and energy to extrapolate several tables
