new here guys and i need help?
just idling and then snapping the rpm's to 5K it would boost and whistle, when driving as soon as it starts to boost it will whistle. does this sound like a boost leak or not? i have the turbo smart bov on and i thought maybe it was causing it so i swapped it out to the stock plastic bov and it made no difference. one more thing, it just threw a P0300 code but does seem to drive ok.
