n20 outlet plate question
I have a n20 outlet plate kit the basic size that I installed on my 99 vette. Every since I installed the plate I have been getting a whistling at low cruise rpm. Ive checked for leakes and I know it is the plate Because we put a n20 outlet plate kit on my buddys vette also and he is now getting the whistle sound also. Is anybody else been getting this sound and any solutions
