you guys have smoke during a regen? this is my first emmisions equipped truck and i got it new. never had the smoke during a regen till now. has 14xxx on it. dealer says it isn't abnormal. kinda a whiteish haze it seems but only when you get after it and kick up the rpm's. normal driving keeping your foot out of it and letting it shift out around 2000-2300rpm, there's nothing you can notice. only when you really lay into it is there the crap out of the pipe.
