Hello, everytime I accelerate up to and over 5000rpm I hear a kind of dump valve noise similar to the noise you get with the boost return mod. but I havent done this mod yet. Ive just recently installed my induction kit for my g40, k&n cone filter and piping, and Ive only started noticing the noise, would this have anything to do with it?
My car is completely standard appart from the induction kit and the noise doesnt happen lower tha around 5000rpm, strange?
Its making me a bit paranoid, dont like strange new noises comming from my g lol...
any ideas?
thanks, Adrian.
