at what point do you need the s-afc ?
will you benefit from it if you are running the stock turbo and inj ,or dod you at least need bigger secondaries ?

 

If you're running larger-than-stock fuel injectors, I'd highly recommend one.&nbsp Other than that, once you have all the base upgrade mods done (upgrade fuel pump, exhaust, intake, etc.), the S-AFC can be used to fine-tune your fuel delivery to get back some of the lost mileage and power due to running slightly rich.
