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.
Ok I checked it out in 80 hp daily I run about 2-3 psi. In my 120 race or 140 extreme I see 2-4. All of this is at 60 mph. It wont really go up much more than that unless your on the loud pedal a tad. However, if Im making about 3 psi with cruise and I hit the throttle a bit it will shoot up a bit. All depends on throttle position and percentage. My gauge will flutter a bit if Im accelerating but if I am cruising, it will remain steady.
Rocco, I have to bet your reading are normal. Mine flutters a bit then when up to speed steady. My egts run about 550-600. Sounds normal the only thing I think you should see is a few psi towing. What is your speed and rpm that you were talking about in that towing situation?

Mine doesnt really make any boost till about maybe 1500 or 1600 rpm. If cruise control is on it doesnt give it much it much gas with cruise control unless you go up a hill or something so thats why when cruising it dont boost much
yea before i had gauges i had no clue how little boost you make just cruising, i figured i made more than that but it makes sense because there is not much load on the engine so you wont be making much boost
My gauge has never fluttered.
3-5 avg boost on cruise
10-12 merging on to hwy from on ramp 40-50% throttle
most i I have ever seen is 28 and surgin like a mofo
I put a autometer gauge set on mine recently and got a lot of gauge flutter. It basicly needs to be a liquid filled gauge to stop all that flutter. I got a partial fix by putting a fuel filter on the tube to gauge. I used a plastic fuel filter and it reduced the gague flutter by maybe 75%. My boost pressure is totally dependant upon throttle setting, can be at 0 at 70mph.
It must be different w/ the 6.0's then. Because everybody I talk to w/ 7.3 says 6-7psi cruising on the highway. But boost is pretty much always dependent upon throttle positioning, load, and rpm.
Doing 70 i make about 6 or 7 psi but you have a 6.0 so the turbo is electronic and everything. Suprisingly I figured cruising the 6.0 would make a good amount for fuel economy

Not exactly. Without more fuel it won't boost more PSI.
