turbo boost psi
If this has been addressed I was unable to find where. What is normal turbo psi at 65 mph, auto, 373 reargear. My 05 6.0 gauge shows 5 psi. My best all round mpg is only 16 mpg. Also when engine is shut down after idle, I can here turbo slowing down. My 01 , 7.3 psd didn't do this. Thanks.

Thanks Todder, any opinion about the noise the turbo makes when winding down ? It sounds like a bearing to me. I haven't taken the truck to the dealer yet, I wanted to hear from you all.

Its just the turbo slowing down. These are a bit louder than the 7.3's. I just put 4" exhuast on a buddy's 7.3 the other day and the turbo took a minute to slow all the way down. I think it sounds great IMO.
Yeah the cat back will open up the sound a little. Nothing is wrong totally normal.
