Ah, the DPF delta sensor.. That needs to be plugged in.

What is this phantom code you are referring to? is there a number with it? I have not seen a single blip on mine since I installed it per MADS instructions with only the Delete pipe for the cat/dpf. I do have the O2 sensor still hooked up.

With the power derate you are describing, it seems like the EGR motor is not getting sensed. That gives a 40hp derate.

no codes at all, just a dinging overhead ....

once i "clear codes" when there aren't any in there, it's all better and goes back to it's normal self.

i got an 07 with the 6.7L and i cut everything off but the dpf and i get a check engine light and the cat 100% sign up top and a decrease in power and every now and then an extreme decrease in power and just rolls black smoke out for bout the first 3 gears. Would getting a smarty to fool the computer to think the cat is still there fix all of this? and also it had an edge juice with attitude on it but i hated it and took it off, couldnt tell a power differance at all.

08 3500 ram 6.7 manual shift. used commercially. 167K, dpf/ egr delete. k/n air filter free flow exhaust. smarty tuner running level 3. same problem here see dealer now in over head. always happens when fuel gauge goes just under half tank. happens nearly every time. noticable miss like running out of fuel. on acceleration black smoke comming from exaust noticable power loss. fuel up run okay but not back to 100% until I reset see dealer now service required. You do this by turning the key on do not start then tapping brake two times then accelerator two times with in 10 seconds. then turn key off for about 30 sec. this resets see dealer now light. then runs great until needle drops below half tank same cr---p again. any one know how to correct this glitch?? real pain and dangerous when loaded and gong up hill and the tining just quits for several seconds let off accelerator then it catches back up ten light comes on on over head. this is getting real , please help dthanks

if you dont notice a power difference with the edge its prolly cause your trucks going into limp mode or not hooked up corectly or not getting good conection somewhere cause i got the edge on mine and i can notice a difference on each setting not sure but just a thought if you put the smarty s67 me should solve your prob im runnig code free also if your truck is cutting out and or when it smokes lose power my truck was doing hat kinda and i put new injectors turbo and ended up being the throttle blade in the driver side of the motor i just bought a delete kit for that and probs solved might try that ??

i think you have multiple issues hl

black smoke means unburned fuel. I don't get smoke. could be your throttle blade closing partially... just odd that yours does it whenever you are below 1/2 tank.

I believe it has something to do with the ECM regen timer. if the truck doesn't regen within a certain timeframe the computer is supposed to initiate an active regen but can't due to not seeing the values it requires to do so.
