Hey Nick, how much have you looked into the zex kit? I'm sure you are tuned, correct? Currently, I am not, but the ZEX kit says that it monitors the AFR using "active fuel control", which monitors bottle pressure and makes sure the engine never runs too rich or too lean.
I know i need to get a tune for the bolt ons i have now, but what would a tune do for me if the kit already checks the AFR?
