Put my new 5" turbo back exhaust on my LMM. Holly crap. This thing smokes like a dodge with a smarty.

Can't wait until my EFI V2 makes it to me:gearjamin.

No wonder DPF's suck so bad GM's factory tune isn't very clean:rolleyes:. It's amazing I was getting 16 mpg before.

My buddy, who is a dodge guy, likes it.:cookoo[1]: That can't be a good sign.

If your LMM is smoking with stock tune then something is wrong with it

He's gotta have a tune on it somehow in order to run the "no dpf" exhaust so perhaps he's got it cranked up and forgot to mention it

I won't say it will black out the whole road but its pretty bad. It was dark out last night when I finished. I'm getting ready to head to the farm now to see how bad it is during the day.

Rob is going to be doing my tuning. Just waiting for my V2. With the shortage due to the pre price increase sales. Hopefully it get here soon. :thumb

That's exactly what I would think but no. No tune what soever. Just the 5" turbo back and PCV reroute. Stock other than that.

Well if you did it at night and there was a car behind you, then it would look like a ton of smoke. I remember before I was Tuned I thought my truck smoked but it turned out to be just a haze and the headlights made it look like smoke.

Yeah you're right. It was a lot cleaner during the day:eek:. It still smokes a lot more than I thought it would though. Can't wait for my V2 to get here. Hopefully they are working overtime making them.:drink

Does upgradeing your exhaust cause your truck to smoke? So if I have a stock LB7 and I upgrade to a 5" exhaust I can expect it to smoke?

Just straight pipe it and take off the turbo blower hose. Now the truck is about as fast as a Dodge and rolls coal like one too :rolleyes:
