dpf removal

why would you want to make it smoke?
If you think it makes it look cool when you take off at full throttle and blow a big cloud of black smoke, it would be easeir to sell that truck and get a non-LMM truck, maybe a dodge, they are easy to overfuel and get lots of black smoke(wasted power)....
there's not a lot of aftermarket support for LMM yet, but wait a few months, I'm sure a lot more stuff will appear soon as companies figure a way around the DPF.

Sure put a dpf & cat delete exhaust on it & use efi live to overfuel it.Originally Posted by marwan286
Why ? black smoke = unburnt fuel

Buy an old beater with bad rings, it'll smoke. Seriously though, wasting $3.25 a gallon diesel aint cool. Some folks have more $$ than sense.

You really don't get much smoke from the LMM unless you do a poor tune. With a stock transmission, you can't hold that kind of power though. I've helped out quite a few LMM owners with the DPF delete idea and the results have been excellent so far...

I wish diesel was $3.25 here....it is $3.59
Jeep & Network Mechanic
Yeah I was being conservative in that estimate. It's $3.29 at the local truckstop, or $3.35,
I usually get mine from Murphy Oil @ Wal-Mart, cheaper, cause they never bother to change the diesel price when it goes up. It was a good $.20/gal cheaper for about 2 weeks after the last big run up

Even when my 02 LB7 was piped and chipped it still did not smoke......never wanted it to.
It ran like a vet but it did not smoke.
