03 Trucks getting new OS

[EC_Tune]

I use calid.gm.com daily and it looks like the 12579405 Opsys for 03 trucks is being updated to 12593058 for Throttle Body coking issues.

Also 99-03 Vettes look to be getting new OS's as well.

Just an FYI

1997-00 Vette OS is getting an update too:
9355171 is being replaced by: 12593456
Reason:
New software to correct fuel disable feature not functioning after a battery disconnect or BCM loss of communication.

Opsys: 12584929 is being replaced by: 12593359
Reason:
New software to correct fuel disable feature not functioning after a battery disconnect or BCM loss of communication. Replaces all previous software.

This is an opsys change only and uses the previous Engine, Trans etc files.
