Codes P2563 and P003A

I am running a DSP5 switch and tunes from Duramaxtuner.com. I have both codes P2563 and P003A. I have already replaced both the vane control solenoid and the vane position sensor but it still throws the codes after a while. I've never had this problem before when running stock tuning. I'm wondering if it's an issue with the EFI programming. Also I've noticed that when I first start the truck and start driving immediately, the truck won't build any boost for the first 10 or 15 seconds. After that, it builds boost just fine and drives great.

Any suggestions?

You could of tested both the vane control solenoid and the vane position sensor so you didn't have to replace them. Take the EFI programming out to see if thats the issue. Search P2563 and P003A Lots to read from how to clean the turbo or have it replaced to many other things that might be the cause. Heres just two Threw a code. P003A and Dealer giving me new turbo!

The first thing I did without testing anything was change the vane position sensor. It didn't fix the issue so I then took it to the dealer and they tested everything and did a vane sweep test and determined it was a bad vane control solenoid. I bought a new one and installed it. It did help a whole lot on the power. The turbo is a lot more responsive now. After a while, it threw the two codes yet again and I'm just about out of ideas at this point. I would remove the EFI programming but that is not an option since I sent in my ECU to have it re-programmed. I wish I would have kept the stock ECU.

Ever get anywhere with this problem?

I'm having the exact same issue, DSP5 switch and tune from Duramaxtuner. Have been running the tune and switch for at least a year with no problems. But the past month I got both codes. I have EFI live capabilities, but have not messed around with it too much to do any diagnosing.

Think I'm going to take some time today and learn more about using EFI to its full potential. In what capacity can it function like a Tech II? Can I use it to cycle the vanes and check the sensors? Would love to test em before spending the money on 2 new senors/solenoids. If they're fine, sounds like I might need a new turbo, time to start researching the aftermarket options!!
