Hello, you might try a new fuel rail pressure sensor. This Code 0088 is for high pressure at the fuelrail. It would be possible to rig a testing pressure gauge to the truck and drive it to see what the pressure really is. If the dealer has a Dyno, he could run it in the shop.
Some of the reports I am reading is the Turbo boost for other owners is starting to max out about 70-75 MPH with a load and usually going up a grade before this light comes on. A certified Pressure gauge would show whether the sensor is tripping too early.
I want to believe there are some specs the Dealer could use to bench test this sensor. But if the end result is buying a sensor and paying Labor you could just go Aftermarket and install a New sensor yourself.
Would like to know the final solution on this.
