Lots of smoke and loss of gas mileage

[Making Strides]

Just started rolling a lot of black smoke at take off and when the throttle is touched when driving. Gas mileage has dropped off noticeably.

Where do I need to begin trouble shooting?

PLEASE do not use the term GAS when you mean either diesel or fuel. It can cause many unpleasant communications problems.

Sounding like a computer problem.

My bad about the gas comment. I have a sct live wire programmer. Do you think I should put the factory tube back on. Also I just had the the injectors cleaned, vacuumed, at the dealership. After that is when the problem started.

Start from scratch. Disable the SCT and see how it reacts. When you had it at the dealer for the injectors, did it run good afterwards?? No problem about the gas comment.

It would barely smoke at takeoff and it would roll the smoke heavy if I stood on the pedal before the trip to the dealership. I had the cleaning done as a part of maintenance per service manager. After that is when it started to change and has gradually gotten worse

You have something wrong get the tuner off and get it back to the dealer.

 

[DaveBen]

I think Dogman is right. Remove the tuner and take it back in to the Dealer.

I have a funny feeling that the dealer is not going to claim fault and probably blame it on me since it has aftermarket mods done. I will give you an update as soon as I'm done.

Thanks for everyones help.

/rant: You knew this when you installed the aftermarket parts. You should have waited until the warranty ran out before you installed the tuner. /rant off: It is your truck. What are you going to do??
