Just put 100hp injectors in last week and now when I get on it enough for my truck to blow some smoke I have it comin through the air vent too. only when air is on and when I poped the hood on it and had my friend hit the throttle it was comin some where by the turbo but don't know where. Has anyone heard of this before if so please comment

i had this problem once it was the band clamp for the down pipe, it was leaking

yes,likely just an exhaust leak at the band clamp.

The smoke is bad enough now, that it must be getting sucked into the cab fresh air intake
