Black smoke is unburned fuel. On a stock duramax you should not see black smoke. Now, one with a few upgrades, some black smoke is normal. With many upgrades the more black the better!

Nice to see, but in reality it's just potential horsepower escaping.

I get NO black smoke with my 95hp setting on the Power pup. I think it means its a good tune but I would like to see some every once in a while

How many miles are on it. When I got mine at 66,000 it would put a bit out barely noticeable. You might see a little.

the more black smoke you have the more nitrous you can run to "clean it up"

Mine puffs nice at low rpm on setting 5, but once it spools, it is clean and gone! The blue streak has arrived. Dont blink, or you will be blown away.

Black smoke means accelerated maintance on engine fluids also ... Tends to leave soot on more then the rear quarter ...

It's amazing how fast the jap traps back off when they see the black smoke pouring out. They probably figure my truck is about to blow up. (They might be right :)

Black smoke is good for covering idiot drivers with as you pass them...


I just coated one yesterday. I followed him for 5 miles doing 30 mph on a 55 mph highway until I could pass him.

My stock truck would smoke a little at 60,000 miles.
Would smoke a lot if you took it easy for a while and then stepped on it.
Now with the juice on 3 it smokes a lot. Throws out big clouds like an old Mack truck.
