Boost gauge question

[roccodart440]

I want to make sure my boost gauge is working correctly and that my turbo is working right as well.

It seems to flutter and then it comes up to a steady boost reading. Normal?

Going down the road with nothing in tow and on the flat ground it reads zero. Normal?

MY EGT's are around 600 at cruise speed. Up to 800 on a grade of with a little more throttle.

Trans temp 150ish.

flutters from? a stop or in what band?

and i would think it should read something. what speed?

[roccodart440]

Flutters under 10-15PSI

At highway speed on flat ground. Basilcly reads zero.

mine does the same thing, I assume it's normal

[Kyle_KleinSS]

Cruising at 60 mph in my economy tune i only make 2 or 3 psi

[roccodart440]

This is in Heavy Tow

what kind of boost do you see at the same speed with a different tune on Kyle?

[Kyle_KleinSS]

Usually about the same. Thats with cruise control if i go to 140 extreme it might make 5 psi. Ill test it out for sure when I go out

[85_305]

ok good deal keep us posted.
I heard that stock these trucks boost at like 10-15psi when cruising at 60-70mph?

no they dont boost that high normally between 0 and 7 psi. 7 if going up a hill. the only time that they are going to get above ten is if you are getting on the throttle a good bit.
