both controllers wouldn't do much of anything unless you put it on a dyno with a wide band o2 sensor...
if the engine really needs 15% adjustment, and you only adjust it for 5%... it wouldn't really be effective.
tuning only works when you know what's going on.
if not, it's just a guessing game
but between the two, i'd get the HKS super AFR...

I have super afc in my car. But I recommend tuning it with at least an aftermarket intake. Its would be better to wait if you plan to get exhaust or other mods before installing and tuning s-afc.
The reason is that installation and dyno tuning is expensive so I would wait to have exhaust, intake and other mods to be tuned at same time to save some tuning cost. If you tune with intake only and decide to get exhaust later, you have to tune it again to gain max power and to me it is just little waste of dyno time.
Well, personally I am very happy with my s-afc. I have gained significant hp/tq with my intake and exhaust. Next I am waiting to tune it with race pipe and exhaust cam gear.

I had the SAFC, it works well with several mods that the mass air flow cannot fix itself. (intake ,exhaust...) Do not get it to change the stock settings for a stock car.
If you ever get a s/c or NOS you will need something like the split-second piggyback comtroll unit which requires a computer. but you will be able to do a lot more including timing and if you include the o2 sensor reading you will not need a dyno to tune it just record and watch the readings.

ask for Mark
tell him Gary sent you
P.S. this is what UPRD will package eith their S/C kit.
450.00-600.00 worth every7 dime
I just sold my SAFC for 85.00 8 months old. It couldn't handle boost.
