As you can see in signature that the truck is stock except fuel delivery and added a custom k&n bhaf (will elaborate another day). I had to punch it from a dead stop to avoid an accident and looked in the mirror, to see the brain dead schmuck that was about to rear end me, and all I saw was a black cloud. The truck never smoked like that before, no cel, runs great, and only 73k miles. Is this a concern, maybe map sensor not right??

Any ideas, or is it normal?
