i did some more reseach on blue smoke and found regen could cause this is this true? i drive about 8 miles a day for work. do u guys think when i drive long distance thats why im getting blue smoke bc all that junk not burning untill the engine gets hot enough or dont it regen any more since my dpf delete

 

That is why I suggested there may be a problem with the box you have on there. But I honestly don't know what happens when a truck try's to regen with no dpf in place. I would imagine that it would still Blue smoke.

 

my 08 did that after i got rid of the dpf, i had to block off my egr and it quit blowing blue smoke. i ran a smarty s67 , wich will shut off the egr but just let enough buy to make it smoke.

 

I ordered the sinister egr delete last week i cant wait to get it on thanks for the info Curtis I was worried something bad was going on
