I want to get a V-SAFC for my car do i need any other mods in order for it to help improve my performance for my Ep3?what should i do before getting the V-SAFC if anything?

 

Of you do not have any modifications why would you buy it? If anything you would be using it to lean out your car or make it run richer. You could even use a SAFC. Anyways I would not reccomend them either. K-pro is where it is at to tune a car. If you can't afford kpro then you can get this but I would not run it for a long period of time.
