I'm prob going to use a vette os 6l90e? for tap shift, will that be an issue running a 6l80e from a 2010 Silverado? What's the difference between the two? I'll also be using newer vette os with a 2010 Camaro 6l90e. Any issues doing that?

I'd rather use a truck trans os for both applications, but can I enable tap shift direct to the tcm? Like the vette has? Will efi switch work? Has anyone tried a truck os, with efi Tap shift turned on?
