You are probably not finding anything because its called a HKS AFR.

Also I don't see any info about it being a boost controller, but I haven't looked very hard either, so if you want to keep an EBC you have to stay with your EBC. The SAFC is also not a boost controller.

Stealthee its probably the AFR which is an air/fuel controller it is not a boost controller. Keep your EBC and if needed add the AFR. But you really don't need an AFR/AFC unless you plan to upgrade your fuel system(pump/injectors)

Sorry guys my fault I should have clarified more. I have a Greddy Profec ... my car had the hks ebc prior... my buddy wants my hks and offered me the AFR, i am looking to upgrade the fuel system and all once a few other things are set up first, Like a wideband. I was looking to see which AFR was better and if either one worked better with our vehicles.
