might have a problem not sure...
today i was on the high way and needed to pass a car before some road construction and got on it pretty hard but i didnt let my egts get past 1150. Then about a half a mile later when i got off the high way my truck started blowing whiteish gray smoke. after about another mile the smoke started to get darker and finally it turned black again. i've heard this is a sigh of a blown egr. the only mods ive done to my truck so far are an sct and 4in tb exhaust. any help is great thanks!
