2004 CC Cummins, 4x4 short bed. AFE intake and full 4" exhaust, Edge Juice with Attitude monitor, as well as the BD-X monitor.

I received codes P2146 and P2149 this morning on my way up the mountain. I live in Denver (5280 ft) and traveled to Breckenridge (9600 ft). In Denver my truck has not had issues, but when I hit around 7000 ft. my truck has been cutting out, acting as though the TPS (throttle position sensor) was going out. This is with my Edge Juice on levels 1 - 5. As soon as I put it to stock the truck acts normal from what I can feel. This started some time last week but only threw the code this morning when the engine cut out hard running up the pass.

One thing to note, I really noticed this when I put ULSD in the truck, along with Power Service.

I will be changing my fuel filter again in case that is causing a clog, noticed only when the Juice is trying for more fuel.

What do you think this is? I know it is something with fuel delivery, but is the issue with my truck or the box? In Denver the box and truck seem to work fine, only seeing the issues at altitude. Take the box power to zero and it runs fine regardless of the altitude.

its a malfunction in the junction or box, talked to edge tech and they agreed they had a glitch in some of their boxes but didnt know how to fix it yet, they sent me a new box sayinf that this one may do the same thing so i took it out and left it out for now, the code is cyl 1-3 misfire shorted high or low, cutting out 3 cylinders occasionally its retarded when this happens i had the same thing, i have a brand new unit now but did not try it yet still running the bdtd with outlook

Any thoughts on why this would only seem to occur at higher altitudes? I will try and get in touch with Edge. Being it is now Sunday I'm not sure if their tech lines are open or not.

Any more thoughts?

altitude had nothing to do with mine but as soon as it hit the 175 deg mark and me being on the throttle at that time, anyway call them and im sure they will give you another one i had mine for 2 months and then it just started and only did it when it wanted to 1 time out of 20 sometimes .
