i did the throttle body mod and im about to do the rats nest removal. i have already removed the air pump and air control vavle. and put a straight exhuast on the car with no cat. i have an s5 throttle body on my s4 engine. i am modding my engine but i want to keep air conditioning. i know the air supply valve is what idles the car up when the a/c is turned on. by doing any of these mods (i am not removing the bac vavle) will it affect the air supply valve... would doing the throttle body mod or any of the other mods affect the asv or the bac valve?
