First post please help! I Just installed a LSX intake on a 02 C5 vette with a 80mm bbk tb, bbk headers, magnaflow x-pipe, and exhaust, blackwing air filter. The engine now whistles between 1800-2800 rpm I checked for vac leaks and everything seems ok. I've encountered this scenario before on a ported GT-40 on a 306 mustang and determined it was just resonance inside the intake. Is this normal for the LSX or should I be re-checking for leaks. The customer drove it over the weekend about 50 miles and is happy with it but, concerned about the noise. The check engine light has not come on and MAP sensor readings seem normal. Thanks for your help!!!

Maybe you accidentally installed a supercharger.

all you have to do is bevel the sharp edge in the horse shoe looking spot behind in the throtle body opening on the intake. I learned this from fast.
