What is 4A-FE tuning?

Answer by  mammakat (11147)

I'm sorry, the 4A-FE is a Toyota engine, so I am not sure what you're asking. There is a lot of info out there on how best to tune this engine, and you can always refer to the Toyota specs for your particular engine. If in doubt, I suggest calling your dealership.
