Hi all, ive fitted a blitz SUS induction kit to my scooby turbo. it makes a great whoosh (dump) noise when the accelerator is released but there is another droning noise that comes on at a certain point and at certain revs in different gears. I know this isnt a major problem but can the horrible droning noise be cured??????

If you have a MY92-98 car then what you can hear is probably the pwm frequency for the idle control valve which is circa 250hz afaik. If so then nothing you can do ...
