Maverick I think this is start of the new normal where guys like the power and torque without the smoke, in my experience black smoke is wasted power, its fuel that you didn't get the full potential from

My duramax puffs a little smoke with my 415rwhp tune when I stomp it, but it clears up super fast and just hauls

 

I took the truck to the stealership and the said we think it might maybe be an intermittent injector posibly. We are not sure and need to test it more.

 

ouch dealerships like taking money for nothing....

 

Not to get to far off topic here but I'm not saying I want to drown the person behind me in a thick Black cloud! No no, I may be young but I'm not that stupid! Just a nice puff under hard acceleration for a touch of Diesel Class!

 

we can pull your injectors and get them tested if you want.
