What do you guys think? I had my supposedly reflashed with TSB 7-5-4 this past summer.

FYI - TSB 7-5-4 was superceded by TSB 08-26-3.

In this new TSB, it states:

If the FICM contains one of the following files then it has already had the Inductive Heat calibration installed:
ARZ2AH00
ARZ2AL00
ARZ2AL01

I got this today after my truck got the SES light on my way to work. It was a nice warm -5 this morning.

I haven't noticed much difference yet, though I haven't had a start after a cold soak nor a SES light since.

Previous post was just an FYI for reference on the Inductive Heat Flash and how to confirm that you have it (since you stated "my supposedly reflashed with TSB 7-5-4 this past summer").

The TSB 7-18-4 (Issued September 07) just instructs to program the PCM to the latest calibration version to fix (DTC) P0470 and MIL on in cold weather.

I believe you are correct in saying that if the service department applied TSB 7-18-4, it would mean that the latest PCM calibration was applied at that time.

TSB 7-5-4 was the TSB to apply the FICM re-programming to the Inductive Heat flash. This has now been supeceded to the one I mentioned (TSB 08-26-3) which instructs to verify latest FICM program.

TSB 08-26-3
6.0L DIESEL - DRIVEABILITY - NO START, HARD START, RUNS ROUGH - FUEL INJECTION CONTROL MODULE DIAGNOSIS
