So, from what I get from reading all this, it appears that SD based maps provide better all around drivability and better fuel control vs MAF air/fuel control. That being said, with better air/fuel control, don't you have a better chance at making more power vs MAF air/fuel control? Or perhaps you can reach your power goals easier with SD? What I'm getting at here is what is the main benefit of SD? Drivability? The possibility of making more power/tq? Or both?

I would think that if you have MORE "control" over your ECU so to speak, you would be able to squeeze out more power, would you not?

I guess the only real way to tell is to make SD tune almost completely identical to a MAF tune and take it to the track or get it on the dyno. Same day, same temps etc.
