Is there any way we could have the table B5100 Spark AirFlow Axis added to the older E67 (and E38) OSs that don't have it? I cant figure out why some year OSs have it and others dont, 07 TBSS doesn but 08 TBSSs does. Z06 Vettes dont have it at all from 06-09 but 08-09 LS3 Vettes do and the 09 ZR1 tune file I have does. 09-11 CTS-V LSAs do as well.
The 07 Silverado doesnt but 09 Hummer H3 Alpha does.
Doesnt seem to be isolated to E38 vs E67 or even OS to OS. Is it an OS limitation that GM has imposed or is it something that can be added?
