I kind of disagree. If one type of ROM has internal changes that let the car make more power over another ROM then... It doesn't matter what those changes are. Maybe the stock ROM doesn't have the knock sensitivity programmed perfectly and the SD ROM does. Etc. We could sit here and brainstorm endless possibilities as such. But no one can question empirical data.

Run it at the track and see what the car traps. Or better yet, use one of these instead. Just verify the altitude change during the run... Thank goodness for GPS

Notice I said trap speed. I've come across WAY too many people in my life who, when asked what their car traps, respond with '12.xx'. 12mph? Wow, that's slow! I didn't asked for an elapsed time nor do I care!
