Pcv auto tune for dry nos ?

Its a big risk....with the PCV you can hook up a toggle switch and switch maps on the fly (much safer). For a 40 shot you want to add around 25-30% more fuel (dual sets of injectsors) to start then trim it down to a safe AFR from there. Get it safe on the dyno then fine tune it with the PCV thats my advice.
