What are the advantages of having a PFC over an s-afc? My car is running way rich, I want to fix this. Advice/suggestions would be helpfull. Thanks

 

What mods do you have and what mods are you planning on getting down the road?

 

s-afc is NOT the way to go....I'll tell you that much !

 

AFC is a piggy back system that works with your sotck ecu. It will let you add or subtract fuel by 50% and does not eliminate the fuel cut. If you are planning on modding your car then I would get the PFC, it replaces your stock ecu and it'll let you control fuel/timing/etc...etc...

 

I wouldn't say all that. If his car is pretty much stock and he wants to keep it stock. And if it's tuned right the S-AFC is just fine. Although I would recomend the PFC, mostly because hardly anyone wants to stay stock.

 

I'm with the PFC. That's the only way to be sure you'll get exactly what you want. Plus it saves you the hassle of buying both a boost controller and an air/fuel controller. There's lots of neat programming options with the PFC and it'll be better for modifying your car down the road because it can compensate for the effects of upgrades whether they're exhaust, downpipes, intake systems, turbos, or even intercoolers.
