i just complete exactly what you want like 1 week ago.. you need to open you ecm and check if it has the internals that controls the IAC valve, check here: www.lt1swap.com
if your ecm does has the internals that controls the IAC valve then this is what i did:

on the tune file depot webpage i find a 04 or 05 GTO manual calibration, this one uses a 1mb ECM but still uses the drive by cable, then i did a full flash, then changue the parameters on the tune to suit your engine, like displacement, spark tables, VE tables ,, and it is runing just ok now

I moved this to Conversions if that's ok.

400ss does the gto tune fit the truck wiring harness?

EDIT -

The 1 MB GTO tune did not load into my '99 512k computer.

Used an automatic tranny truck tune with the automatic SES codes turned off. Works great.
