I'm stranded at a parking lot because my truck has not throttle what so ever. Running SCT extreme with dpf delete and it's giving me U0101 and U0115 codes!! I set it back to stock and it cleared up but it wants to clean my non existant dpf.... Loaded the tune back on and the same thing started happening again. Any ideas??

there is no u0115, but there is a u0151
"U0151 Lost Communication With Restraints Control Module (RCM)"
and u0101 "U0101 Lost Communication With Transmission Control Module (TCM)"


to me it sounds like your sct isnt talking to the compuers right.

The u codes are nothing, there not the problem. They come and go on there own and only mean communication stop between components. It sounds like you may have a corrupted file though. Try setting it back to stock and then reloading the tune.

Ok I towed it home, tuned back to stock, put dpf back on and now it idles fine, but runs like total crap!!! Can't build hardly any boost and I'm blowing black and white smoke with the dpf back on? Guess it'll be going back to the dealer.... Anyone with any more ideas?? Thanks for the help!!

Maybe a bad sensor. I remember I unpluged one of mine on the intake elbow to tap it for a boost gauge and forgot to plug it back in and it smoked like a freight train and threw a wrench sign every time you hit the throttle but as soon as it setteled to a idle it went away and it drove like chit then I remembered I unplugged something and it went away after replugging it. To me it sounds like a bad sensor so thats a place to start, dosnt sound like a hardware problem.

I had an EGR sensor go bad about 2 years ago or so. It took everything the truck had to get up to 50 mph. Coolant got on the sensor and caused it to go crazy if I remember correctly

P0404 and P1335 EGR codes and a P1000 are all that are showing now. Yeah only 20lbs of boost and hardly any pedal... Takes about a mile to get to 60mph. DPF on now and stock tune. Tuned it will hardly idle and have zero throttle!

it basically says the circuit is out of range. I'd have a hard time believing that is anything but a sensor.
