i installed it last night on my 2011 along with a 5 in flow pro straight pipe exhaust even on hot it don't smoke just making sure that is how it is or is there something i am missing here

 

Not sure how much hp hot is, but my truck doesn't smoke on the 90hp smarty tune.

 

well it clamins to be 175hp on hot but it must just be a no smoke tune because it wont smoke at all

 

I think these good programs/tunes from these quality Program manufacturers really don't allow for smoke anymore because that is wasted efficiency and a red flag to all others you are breaking Federal Laws.

I am very happy the tunes don't really smoke.

There are other mods you can do, like the "smoke swithch", to play Smokey the Bear putting out a fire if you like that which is fine in my book on an occasional basis .

 

I have to agree with mega on that. Plus it just makes it all that much cooler to out run a smokey ole 5.9 when you aren't smoking.

 

mega this is very true i do like it i was just making sure that it was supposed to be that way and speedy i like the idea of out running some old 5.9 and seeing there face when it don't smoke at all buy the way this is my first cummins i have had two duramax 03 and 08 buy fare i like this truck better fills more like a truck
