[jasonsimons]

I have a 2002 3500 DMAX witha utility box on back. It is my work Truck and I cant make any money cause Hanks down! Runs fine then bamb a Whit puff of smoke engine chatter then back to running awesome again. All stock but air filter. K&N drop in. It seems to do it under load up a incline. I replaced the boost sensor and nothing. No, engine lights.... Help

Usually white smoke (in most cases) are unburnt fuel. Start with checking your injector balance rates. Sounds like perhaps you have one sticking thats why it is intermittent. Run a good non-alcohol additive or run some 2-stroke oil through it. See what happens
