‘96 LT1 to 12200411 PCM conversion

Hello everyone!
I know this has been brought up several times in the past, but I am trying to be clear on how
to get my PCM programmed with the correct “Express Van L31 Tune” I just re-pinned my harness
on my ‘96 Trans Am, I have the LS Droid app, OBDLink MX dongle, I have flashed my PCM
with an express van tune, but I am unsure of which one it actually is, and what the correct operating system needs to be installed on the PCM. I know it needs to be the L31 Vortec 350 one. I followed “ Horsepiwertubes” pinouts as instructed on his facebook page, but his notes never made mention
of deleting the “ Cam position sensor” in the tune.
could be the reason my car isn't starting, I don't know.

Can anyone point me to the correct “Express Van” Tune for a L31 350 Vortec?
and the required XDF/files needed to get this going?
thanks!
Ben Smith
