Sleepingtsi95 said:ok guys, check this out when im driving and i let off the gas, there is a slight whistle that goes for about one sec, i thought it was just me but i had alot of friends tell me they heard it. -the noise almost sounds like bad breaks but waaaay softer. its obviuosly not the brakes, and i thought it was the clutch but its definately making the noise when i let off the gas....what is this NOISE!! i it good, bad or does it matter at all?????- sorry its driving me crazy
Yunebug said:Yes, that's what I found as well. I replaced the 1G with a HKS SSQV with recirculation kit, and the whistle went away! YAY!
...then another problem. I've done some research, and I found that HKS SSQV flutters... whistling is gone, but not it flutters. (sigh).
SO I've gone back to the 1G BOV. Anybody want HKS SSQV BOV flanged for 1G?
