Silver64 turbo is a great addition. But I have questions. Sometimes right before and directly after a shift, I'm hearing a "whooshing" noise. Is this surging or barking? I don't tow anything and it doesn't sound bad, just different. If I get off the throttle too quickly while boost is high I hear what must be a "bark"... sounds like shutting off a high pressure air line a couple of times quickly in succession. This too doesn't sound all that bad, but I've never had full boost and immediate foot off of throttle. Bet that wouldn't sound too good...

Any opinions appreciated...

 

turbo bark. its not too bad unless it shakes the whole truck LOL, which i have done on my stock turbo

 

Thanks... that's what I was thinking.
