which would be better for fuel management to controll 450's? they both lean/add 50% fuel trim but i think the hks has more rpm increments or i could be wrong!?! just wanted to know your thoughts on both. i know everyone uses the pretty SAFC but it looks as if the hks AFR is pretty damn good too! the hks has a built in cpu thats helps makes adjustments for fuel? so it does some of the work for you?? i'm unsure of which has more advantages...help

 

basically does anyone have any thought of the hks afr?? it has a built in cpu and i'm not to sure what it does or if its any better or just as good as the apexi safc? i can get them both for the same price so which would benefit more? anyone
