hi everybody
the past three times i have drove my 08 lmm as i am driving down the road just cruising around 55-60 the truck looses power. I then lay into the throttle and it puffs a lil smoke, just kind of a haze but no power still. I can let off and let it coast for a couple of seconds then push on it again and its fine. this happened on three different occasions. Has anyone got any ideas why this happens? Is it in my programming or something else? I havn't changed to a different tune yet. no dpf by the way. thanks
