black smoke when shifts and turbo pitch change
okay well when my truck shifts some times it smokes black smoke not a ton but alot more then stock trucks will smoke if you know what i mean. and then when in overdrive and i get on the peddle, not enough to shift, but enough that the turbo will spool up i can hear the turbo whistle and the pitch of the whistle changes some and then the truck will start to surge and blow a little smoke black smoke when it surges. any ideas whats going on? thanks fellas.
Forgot to say this is when the truck is stock, i havent had the tune on the truck in a while so its been stock for a while and im not getting any codes.
