Code P-1656 on all the time

For quite sometime now I have been driving around with the SES light on not thinking anything of it finally I checked it and found two codes P-236/P-1656. I did fix the 236 but still have the 1656 its really bothering me cause if i clear it the truck runs awsme turbo winds perfect, then it comes back on after restart and everthing is crap. I cant afford the turbo master yet but its on the wish list.one more thing if some one could send me a pic of where the orange and black vac lines go on the waste gate side (orange front,black back)???that would be great.

So do you know what is wrong with your truck? Is it just a line, or the vacuum pump/solenoid/actuator? I have whole good vacuum system here, minus the lines if you want.

Also my truck has a under hood sticker that shows where the vacuum lines go.
