2008 6.4 Overboosting/Loss of power

I have a 2008 F250 with a Spartan with KEM tunes, intake, exhaust. In the last week it has started boosting really high and there is a loss of power. I can easily hit 50+ lbs of boost at mild acceleration. Does anyone have any ideas?

Does anyone else have any input on this? Truck was in the body shop for a while so I didn't have a chance to mess with it but I still need to fix it. I've also heard it could be a sensor. The VGT linkage moves freely when the truck is off.

Both codes have to do with turbo over boost..and turbo sensor....Make sure your air filter is clean, dirty one will cause high boost.

I have been fighting with the 2263 also. It says turbo overboost, but I will throw it when I am cruising. I replace the Exhaust backpressure sensor which is the sensor you have to replace and it did it once again right after I installed the sensor. I have not seen it since and it has been about 400 miles. The other thing could be the VGT like mentioned, or a leak in your air intake somewhere, or a exhaust leak.

I would replace the sensor, that is what I believe was wrong with mine. Some guys say they pull the line off that the sensor is connected to and clean it. I think that is why mine gave me a CEL again, because I did not clean it. I know it is fixed because I could not get the 2263 to clear and now it is fine. The sensor was $86 from ford.

The sensor is located on the driver side in the back on top of the valve cover. It is brass and connected to a siver tube at the bottom and an electrical plug on the top. If you look straight back from the middle of your battery you will see it no problem. Took 3 minutes to replace it. Good luck.

When this was happening did you have intermittent power during hard acceleration? Mine seems to be creating a lot of boost at low RPMS ever since I blew my silicone boot off the hot side of the intercooler. The power seems to pulsate during hard acceleration now? I am runing H&S on a mild setting.
