I have installed part of the Evolve power package -- chip and exhaust -- (and the dp get installed Monday) and I now hear the turbo whistling. Is that expected? <p>I did not think that I heard it immediately, but 2 weeks later am noticing it; function of boost, right?<p>Thanks!!

Re: Turbo whine (jroux)

Does it also sound like the AC is blasting when you step on the gas? If so, look at the hole in the firewall from inside the cabin. There should be a rubber grommet there. It may either be missing or just need to be popped into place.

Re: Turbo whine (frankhoffy)

there is an RPM specific whistle, so likely not that, right?
