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
