I'm not 100% sure that EFI is more consistant then a carb.

Anything is going to change HP with weather changes (EFI or Carb). As long as you have a way to predict that and change the dial in accordingly, that's what's matters most.

So if an EFI motor automatically corrects fuel curves for a big air swing, is that really better? Or does that just mean you're going to have to move the dial in further then usual?

If you were going to index race, I could see where being able to have timing curves adjust for weather conditions as advantagious. That way you didnt' have to move throttle/timing/shift points/weight around to hit the number. But that seems like a lot of work, and probably YEARS of data collection before you could do that well.

I can tell you my scat pack challenger is absolutely horrendous to bracket race with. Couldn't run a consistant number to save it's life over the 70-80 passes I've put on it this summer.

But in all fairness, that is a lot more complex system then what we're talking about here...so not really apples to apples.
