For stock settings are your vafc's set at Wide Thr LVT 20 rpm +-0
Narr Thr LVT 10 rpm +-0

Also if I get my car tuned with a cai and exhaust, then i decide to put on the stock muffler and stock air intake box, will my car still be tuned when i switch back again to the cai Intake and exhaust?

 

say if you wanna play around with your vafc.. you need wideband in your car
so you can set your way through..
so you can set it so it's always running not too rich or lean
