Just wanted to update this thread again, recently deleted the truck with EFI Live and so far the S&S diesel emissions intact CP3 has not given me any issues running deleted. Seems kind of stupid to buy the emissions compliant pump I know, but, like I said the idea was to be able to switch back to stock if need be (although the increase in fuel economy and overall fun makes me dread ever being stock again) but yeah, just figured I’d let anybody who cares know that it is possible to run emissions intact or deleted with this specific pump set up.
