Hey there and Welcome.

To answer your question you may have a boost leak or your boost gauge may not be working properly. You should be around 20-22 psi at wot with a load. How high are your egt's getting. 1250 is the cut off for most people.

As for your chip your getting from banks. It connects the PCM under the dash on the drivers side by the e-brake. There are to nuts two bolts that have to be removed from the engine compartment if I remember correctly. Just follow your directions and take your time on the install. I am sure others will post with more information.

There is now way you can up the fuel pressure with anything electrical. You would have to modify the fuel pressure regulator with a spring spacer or higher tension spring out of a California FPR. Stock boost should be around 17 psi max, with a good hot chip or program you can get close to 30-32 psi. Look into your intake at the turbo impeller and make sure you have good sharp corners. A little dust can ruin a turbo and an engine, that’s why I hate K&N air filters, if not meticulously maintained they can leak dust into the engine. A turbo diesel pulls a very high volume of air which can overwhelm most air filters. Take a look at my filter. Shutterfly | Slideshow

well whatever it may be,maybe i obviously explained it wrong to you.I have seen these before but never looked into it because i never had a powerstroke.It is a switch that hooks to the electrical wiring that has to do with the gas pedal and it sends some kind of a signal that makes it read more throttle than you are actually giving it.It some how through the process ups the fuel pressure.

I hate to be hard to get along with but the fuel pressure is constant no matter how hard you mash the fuel pedal or how many rpm you are running. There is no way to change it while driving. Stock it is around 50 psi and with a FPR mod it can be around 80 psi. No big deal I just want to make sure we all understand how the system works.
