Trying to find out if our 7.3 is tuned or not
We bout our 7.3 excursion with a 38r turbo, intake and exhaust. Supposedly never had a tuner on it, yet from a stop throws out a good amount of black smoke. Also, at WOT it hazes black smoke. Is this common on 7.3's? The thing only has 188k miles.
03 cummins - litte of this, little of that.. Tickled 700hp early 2013
