Chevy 5.3 swap I have a computer that came with my 5.3 motor and the throttle body was a drive by wire but I bought a new intake manifold that has a mechanical throttle body. My question is do i need a different computer since I changed my intake

This depends on the computer. I believe P01 computers have the IAC driver regardless of their configuration, so they *should* work so long as you can flash them.
The difference is a drive by wire TB manages idle by the throttle blade position whereas a drive by cable TB needs an IAC stepper motor to maintain idle. Some computers (typically later models) do not have the stepper driver as they were drive by wire only.
someone please correct me if I am wrong.
