as some of you may know im having problems trying to find out a horrible noise on the car which starts around 3500-4000. at first it was thought to be a boost leak but it appears there is ALOT of gas coming from the exhaust. was suggested that it could be exhaust by a guy who tunes cars and since i had a powerflow put on i thought this may be to blame so i removed it and ran the car without the rear section. when i did this the "jet engine" noise was louder so its not the new exhaust but i was thinking is it possible that the vvt isn't setup/working properly and is opening the exhaust valves too late and the inlet valves open causing boost to flow staight through causing alot of air to flow through the system.
any help would be great as this is bugging me now.
cheers
