My gauge//turbo or something in between?
Twice I've had my turbo gauge up to 30psi and a few times up to 27psi. On the way to town the have contruction on the little right where you dump on to the big road. Your leaving the little road at 30mph and dumped right on to a 70mph big road. The merge lane is very short. Of course the big road is busy. Any way I have romp down to get any where close to getting any kind of speed to get out there with everybody else. I got to noticing my gauge only showing what I guess to be 9psi. My truck is'nt lacking any power and its jamming at 3500 rpms and wont hit 10psi. From a dead stop I can hit 4000 rpms for split miliseconds mostly though around 3500 and base out around 90mph before I let the pedal up. Still only 10psi. My line of reason is if it where the gauge then it would'nt work at all. If it was the turbo the I'd have tell tale problems.
For info purposes: My turbo gauge is t'ed into the map sensor{I believe thats the map sensor} . My truck is an 04 stock. The gauge is an isspro I dont remember the model the paper work is packed up. I'm in the middle of a move. But anyway my gauge goes up to 60psi. Thanks in advance for any ideas.

sorry to bash bro, but what the hell are you saying ???
your post is hard to read and i dont even know what you want... please try to get a grasp of the english language, or have someone that knows it type for you because it is very confusing trying to figure out what you are saying.

Ah I got exiled 
Most don't agree with using the Map Sensor for Boost readings.. Causes a lot of inaccuracies.. If you are not feeling a loss of power then my best guess would be faulty readings. I would tap your Intake Elbow for the Gauge and move it there.. It's a much better place to get your boost pressure.. On average you should pull 20lbs at half throttle and max throttle would be 25-30lbs..

I believe he is trying to say that when he stomps on it he isn't seeing more then 9 or 10 psi boost, despite the fact that he knows that it can get up to 27 or 30 psi, and he is wondering if it's the gauge or something with the turbo. It could be something with the sensor, I'm with you and thinking that if it's the turbo then something else would be going on along with only getting 9 or 10 psi.

Exiled, You may just have some dirt that got in the line, or a break in the line going to the gauge. If you can, try and trace the line back to the cab and see if there is a break. Most probable solution thst I can think of...

exiled,
As PSDiesel60 said check for a leak in the tubing from the MAP sensor to the gauge, loose fittings, something partially plugging the line or if none of these then the gauge may be going bad.
