Who has the best fuel economy of all the tuners being compared here?

Knowing that tuners aim for a margin of safety with their tunes by running them richer than OEM,which company has the best gas mileage with say a stage 1+ tune(race gas tune) without any other modification?
I realize that it also depends on how many WOT runs you do per tankful!
