Hey there, I’m pretty new to sr’s as this is my first s13 with one. I have an AEM wideband and during idle and cruising along it’s between around 14.3 and 15.5, but when I step on it And hit boost it runs anywhere up to 17.7.
I have a HKS EVC III boost controller, but it’s currently off because I’ve yet to figure out how to use it and I don’t want to go around and just change numbers. So the car is just running stock boost.
