You'll have to forgive my somewhat dated suggestions. I've been screwing around with this stuff since the dark ages, on a wide range of systems. The tps substitution (at idle)is the method I prefer, because I'm familiar with it, and it works well for me.
I believe it was Motorola(?) that came up with engine position map sampling that allowed early efi on Harley Davidson engines to use 100% speed density on a very poor map signal engine to run evenly and consistently. These systems were programed to use a narrow window of map signal in a determined engine position(where the map signal was consistent and strong)and ignore the rest of the map output.
I admit that my exposure to more modern efi systems is limited. Is the holley system capable of adjustable map sampling?

This is thread is a great example of why you should buy the system that the tuner you will be using recommends. Everybody here has their reasons based on past experience.
