I noticed from the factory the L76 in the G8 GT has an area scalar of 4725 and ls3 vehicles (like the Corvette, G8 GXP, and Camaro) are set to 5636.
Is there a size difference between the two throttle body sizes to warrant the change, or did GM make the change in the cal for a different reason? (like the OS differences between the L76 G8 GT and LS3 vehicles)
I checked the repository and a 2009.5 G8 GT uses the larger number, 5636 like the LS3 vehicles. Is the 2009.5 G8 GT throttle body different from the 2008 and 2009 model years?
