Whoosh!

Whenever my truck has been sitting for a few days or more and I go to drive it, it makes this loud air rushing noise from under the hood and the boost gauge doesn't register much pressure... After a minute or so it all go to normal. Kind of sounds like the turbo is just dumping into the engine bay.

Normal or what?

It drives like there's no turbo, but I sure can hear it...

Well I know my fan does that (engages sporadicly on startup), my boost pressure doesn't change, although I'm driving up my lane at very little throttle although at idle or slightly more (Say up to approx 1350rpm) my boost is pretty low (less than approx 7psi) anyways.

If there are no codes present and it feels like it has no boost, then I would check the intercooler for pressure, fuel rail pressure and ensure the all the boots are seated correctly and/or not blown.
Keep us posted,
Dom

I would normally think it would be a boot leak, but boot leaks don't fix themselves after a few minutes of driving.

So does it go back to normal driving or not?

It's not even a few minutes... The longest its taken to get back to normal was less than 1/2 mile. And again, this is only after it has been sitting for a few days or more. About 2 months ago I started driving it about once a week unless I needed to. The dealer is a mile from my house... It would be fine before I ever got there...

It sure does. Drives like the boosted tank it is...


Of course, I said that in the first post, but that's just a minor detail.
