My only concern is when on idle I dont really hear the exhausts sound nor the engines sound and its so quiet unless its a "COLD START" where you can really hear the exhaust soo loud. so i was thinking that the new intake probably didnt kick in yet. Do i need to reset ECU in order for it read the new intake ? or would it read automatically by itself? and if yes how long? Please let me know, Thanks!
