It's more about their MAF housing. The incorporated velocity stack and smoother surface should show better gains than other intakes, even before tuning.
After tuning the Steeda unit will most likely beat the other systems for sure. I'm with you on being skeptical about the 12whp as well, but it would not surprise me if people saw numbers in the 10whp range.
I guess we will wait for people to do more dyno runs and find out for sure.
