Good call on heated air intake, not sure if it is installed on these tug engines or not, but can be accomplished easily. I was informed that GM didn't use intake air temp sensor, so the base map must be done pretty rich it looks like. I have been mulling over the used of ford's efi system on the trucks, but I would need the tug in order to see if it would all fit, as it seems like it took up a bit of space. All good points, I need to do a little research and see where it all goes.
