2006 8.1L IAC PIDs not Valid for RAFIG/RAFPN process

[wrench-head]

I have a 2006 Silverado with the Allison 6 speed and A raylar 202 camshaft with long tubes and Volant. Overall pretty mild and runs great 95% of the time. I was looking to fine tune in some of the idle parameters, but bouncing the needed PIDS off of my OS shows all the ST and LT IAC PIDs as invalid. The 2 calc PIDs for RAFIG and RAFPN are valid and will log, but just rise to 3.88 in imperial or 29.36 in metric units. As such I don't believe them. I've looked around and found a few instances of this, but most were disabling of other parameters etc. I don't have anything crazy done to this tune and have uploaded the stocker as a comparison tool.

I have attached my tune file and a data log showing what happened. Any ideas on the PIDs? I have a 2003 Suburban with the 8.1L/4l80E combo and all PIDs are valid and as expected. Thanks in advance!
