Magnusson moss has some covered.Most tuner companies are awre as well as the automakers,it's their way of beating you outta the warranted work....

That might need to be a sticky. Good find Tyler.

SEMA has nothing to do with it, ther just make sure every aftermarket reseller is aware of it, and no i have looked into before, but it was just brought back to my attention.

Guys,
I just joined the forum, all of you have good lookin trucks. I need to get some pics of my truck soon. Quick question? Do any of you have any good suggestions to gain gas mileage? I have a 2007 LMM K2500 Crew Cab LTZ w/ all the bells and whistles. No mods yet, but looking into it to get better gas mileage. I understand the power will come, but my main concern is gas mileage, any suggestions? I was considering the Banks Big Hoss Bundle, but the engineering department couldn't guarantee more than 2 additional mpg.

Thanks, Pick

Hey pick, If you want to get better mileage on a LMM then you have to get rid of the DPF and get a tuner. I picked up 2 in town and 3.5 on the highway with a truck that weighs 10k. It can get better with a lighter truck.

does grtting rid of the dpf invalidate the warranty

Yes, and if you get caught driving without one on your truck in any state, they can stick you with some pretty heavy fines due to epa violations. Not a good idea in my opinon.
