Default More noticeable "whistling" since installing my chip - normal?
APR Chip has been installed less than 2500 miles. Much more audible "whistling" as I slowly accelerate at low speeds. Normal or symptom?

Thanks for the input..........

Bob

Default Normal,
APR here, and even after switching to Mobil 1 with the stock ecu in, the slight whistle is there.

Default Normal. More boost means more spinning of impellers from Turbos.
If you take out the filter, or put in a more free flowing filter, they'll get even louder.
