Hi I'm new to this site and I want to thank anyone in advance for your help. I have a 98.5 24v cummins and so far once a day when I leave work in the afternoon the truck has low power for roughly 1/2 mile and then is back to normal. It just started this and I would appreciate any help thank u

 

Does it seem to run ok despite the low power?

Aftermarket programmer pulling power during warmup?

 

It runs great except for that,the edge programmer shows roughly 17psi all times and it has crap power when it does this. I pulled codes p0122 and p1693 this morning also? No other motor mods that I can think of except fass fuel system on frame rail.
