Re: Whoosh.... sound During Mid Turbo Surge
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: benny25</div><div class="ubbcode-body">The truck has stock intake, whoosing symptom present when cold or warm. The whooshing noise only is present when accelerating and the turbo spools up. There is no power drop off the truck continues to accelerate.
Before I would only hear the slight whistle of the stock turbo, now its whistling and when I am really on it its a whooshing sound. when I let off the throttle the whooshing sound dies off.
OK, probably not the EBPV as it will usually have a noticable effect on the power,
sounds more like the wastegate is not operating properly, disable it by unplugging the red wire/tube from the solenoid and then drive/test again. just be aware that you can overboost with it disabled so listen carefully to determine if the noise is better or worse
