2000 f250 7.3l no mods other than Superchip cortex

So im driving home from work get about 15 miles down the road and my truck goes to *****. It acts like it did when i ran it low on oil a while back. Or also when the fuel filter is clogged. Just has no power at all. I was able to maintain about 50 mph untill i had to go up hill then it was hard to keep it above 20 mph. It never did stall on me, i could put it in nuetral and rev it up pretty good. but as soon as a load is put on it it peters out agian.

Plugged up my cortex and its giving me a few codes

P0478 exhuast pres cntrl valve high
P0470 exhuast back pres sensr circ error
P1211 ICP not cntrrlab

P0781 1 (all it says under it is 1)

I just changed my oil and fuel filter a few weeks ago and checked the oil today and it looked good.
Any ideas with those codes and my discription of the problem? Anything will help. Thanks

 

I'd start with unplugging the ICP and see if that clears it up. Then maybe clean/inspect the EBP Sensor.
