    Found this thread and downloaded the epa2010 file. Looks like it's password protected. Don't mean to be a bother but I've not found it anywhere in the thread, would you be willing to share the password?

    600 bucks gets rid of all your codes and keeps those wheels turning. Best $$$$$$$$$ I ever spent.

    Pittsburgh Power max mileage will 100% fix this code it makes your exhaust run hotter through the dpf system, wish I had known about it 4 months ago before replacing both nox and several other sensors. 1 Oz per 25 gallons but around $140 per half a gallon. But it works, I wish I would have ran it 200k miles ago. Engine would have less soot
