although it seems to be running ok, my 05 f-250 is smoking way too much at idle when warm and belches big puffs at take-off. smoke cloud is distinctly white and has off odor (not the typ. diesel smell). i got recall notice 05E15 and initially ignored it because a)i've added some aftermarket mods (edge juice w/ attitude + magnaflow 4"+ air raid + sct flash) & b)at that time truck was not smoking abnormally or otherwise acting up. then seemingly overnite its suddenly smoking like crazy! so i reluctantly take it in for the factory re-program (after disconnecting the juice) and here i am still smoking like a chimney. dealer says give it 100 mi to break-in but i'm skeptical. needless to say, people around me a traffic stops are not happy, nor am i. what does the excessive white smoke mean. what will fix it? new egr valve? hfcm? please advise
