The FAST systems do. Besides, getting the fueling in line is easy. And if the system is always learning from the WB, what happens when the controller or sensor goes bad?
I could ask the same question about fuel only EFI systems. Why buy one when spark timing is more important?
The difficult part is getting the spark timing correct. Not only at WOT, but for street driven vehicles it is important for drive-ability.
