I just got my VAFC today and will be getting it installed and dynoed. I just wanted to know how lean is too lean when it's being dynoed.

Thanx,
Chris

 

I think most people (NA) that I've seen tuned for around 13.7. It may depend on where your wideband 02 sensor is, though. If it's a tailpipe sniffer, I think it reads a couple of tenths leaner than it would if it was connected to the header.

Wait until you get more feedback from others, though... don't take my word for it.

Thanx alot for the link as I know there are many others relating to dyno tuning the VAFC. I'm excited to dyno it yet nervous at the same time.

Thanx,
Chris

 

should it be about 13.7 if you have a supercharger aswell?

thanks

mine is at 12.5 measured at the exhaust with the vortech sc
I think it's a little bit safer
a lot more fuel consumption though
