Each PCM was read with: PCMHacking.net software, TunerCat, HP Tuners, and EFILive (twice - once with V7.5 software, once with V8 software).
The PCMHacking.net software had very respectable read times (see attached PDF chart), and saved a *bin which was readable by the other softwares - therefore in no way corrupt.
The only minor issues (which are more aesthetic in nature than functional) were that the PCMHacking.net software identified all of the PCMs as being 12200411 variants, and indicated that all of the PCMs were locked (which technically they are, by the OEM - however most tuning software with this parameter use it to indicate a tuner lock / custom lock of some sort).
Awesome work Antus !
Attached is a PDF chart of areas I examined, and the results between the various software.
