I'm gonna guess you would have to take it back to stock first. Put everything back and then see what it does. If nothing happens, take it to the dealer

 

Nope,you will need to get the proper tuner to fool the ecm into thinking it's still on. Then you can get it out of limp mode.
Or put the dpf back on and let it run through a regen cycle.

 

update.. bought a smarty jr off of a buddy of mine.. still says dpf full. tommorrow ill put the dpf back on.. and hopefully it will regen.. then install smarty jr again and see what happens.

 

Make sure you have the ME software loaded on the Smarty Jr.

the smarty will do what you are wanting if you put the me file on it like luke said.

 

update once again.. UPDATED the smarty jr with the ME software. also got ahold of a plasma cutter and some scrap metal and removed the egr system completely, installed the egt probe on the back port on the egr cooler cap. uploaded the 70hp tune on the truck with DEFAULT timing on the smarty, Now i still have the edge juice with attitude runing on level 3 with the JUICE timing on it.. is this safe? I enjoy the display due to i can read multiple parameters... oh yea. no cel and the tires cant hold traction in 2nd or 3rd gear..

 

i run my juice with no power. the smarty does my tuning. juice is for gauges

 

yes sir that is what I'm gonna do as well.. Thanks again for all of the help on this.
