if you want smoke out of a box, you won't find something that the stock transmission will hold well. Allison only tolerates about 90 hp over stock trim before constantly limping and breaking stuff... Smoke in a box comes from over-fueling in the tune... so, throw that tune on, put your foot into it to get all your annoying smoke, and OOPS there goes the P0700 when your transmission limps.
Best thing to do is avoid the smoke. If you're that adamant about finding it. The best "smoke box" is your stock air box with a towel stuffed in it. It'll smoke like a train.
PS, you've just labeled yourself in a not-too-bright-and-shiny way with your second post saying "I want smoke." Like a drive through Texas, I can see flames on the horizon.
Listen, Smoke isn't professional. It doesn't mean more HP, It doesn't mean your fast, It is going to get us all screwed with diesel emissions. Please don't be selfish, and think of the whole industry, not just yourself.
I am glad to hear that the majority of us on here despize smoking diesels. I cant stand the dam dodge owners around here that have stacks and smokes just sitting at a light . I find it emabarrasing that they have to smoke so much like that just to move itself.
