Limiting boost
 

i know there is no easy way to limit ur boost but i want to be able to be running 10lbs on a norm day but turn it up to 14-15 when "needed" but see what the mods i am planning on getting my car isnt going to be running 10lbs normally, most likely higher. (i wanna lose the cats and i also got intake) either way. i know u need either an external wastegate or u need to mod ur own but can someone who has already done this give me some pointers. oh how/what to do. maybe it is unrealistic of me to want to turn down the boost i dont know im just lookin for a few pointers
