6.0 Questions

[Okiefromwatonga]

OK so I am new to the 6.0 as I just purchased a 04 11 days ago. My question is when the turbo is boosting the boost gauge flutters some (3-5)PSI and cruising down the interstate the EGT's are 800-900 is this normal? Last, I filled up today and the gauge didn't register over half tank, though it most definitely is full. What gives?

Where is the boost gauge getting it's reading from, intake elbow or MAP line? If it is the MAP line, this may cause the needle to flutter. The elbow will give you the best reading. If it is in the elbow, then you may have a IC boot that has a small hole in it, usually the blue one coming off the turbo. To inspect the boot you might have to take it off, sometimes the hole can be on the back/underside where you can't see it.

How fast are you going at 8-900 egt?

[Okiefromwatonga]

Its Tee'd into the MAP line, should I move it to the neck to get a more accurate reading?

70ish. Sorry forgot not every where is the same. Also it was in mildly hilly country, not flat and level with quite a head wind. But she is empty save for myself, the wife and out 5 and 2 year olds.

Did you fill up w/ the key on? I haven't heard of this for awhile, but early on, that is what was happening. It will correct itself if that is the issue.

The key was in the accessory position so the wife and kits could listen to the music while I filled the tank

I know when I fill up, if I leave it running, It will not register on the gauge for quite some time. When I fill up with the engine off, it registers correctly as soon as I start it. Sounds normal to me.

egts seem high. Mine are 750 cruising 75 on level 5.

That location will make the boost gauge flutter. The best place is the elbow going into the intake.
