  1. Wow! I know for a fact that the service techs at my local dealership don't even know all this stuff. Hell I had to tell the guy it had DFM and not AFM and he tried to tell me it was the exact same thing. I knew it wasnt, but I certainly didnt know the details like this. Very good info. At the same time, it seems like just more that can go wrong if it doesn't work properly when if I didnt have it I wouldn't have to worry with those problems. It blows my mind that this "feature" isnt optional, similar to the ECO button in many vehicles. If I want to use it and save gas, that's great, but if I don't I should have the option not to.
  2. Well I sure hope it wasn't the same engineers that designed AFM. Look, I didnt ask for you or anyone else to give your opinion about whether or not you like DFM or if I should. I asked if anyone has heard of any progress on development to disable it. If you have something relevant to that, by all means please share, but if not why waste your time and energy telling me i need to just use it. I don't tell you how to drive your truck or care what you want to do to it. Dont worry about what i want to do to MINE.
  3. Because of the proven issues AFM has caused, and because I have corsa exhaust and it sounds like ass when DFM kicks in. I really dont care about the fuel economy. I didnt buy a truck with a 6.2 for gas mileage
  4. Has anyone heard any news on a device or programmer that will get rid of the DFM yet? Sucks having to ride around in L9 all the time
  5. Clay, polish, seal, and wax. All done with Menzerna and McKees so it wasnt just cheap off the shelf crap. Can't justify dropping $1500 or more and not having my truck for 3 days to do ceramic coating.
  6. I've noticed for a while now that my truck's clear coat didnt have a very slick finish to it. Thought maybe it just didnt get a good coat of wax or something maybe, so I waxed it with some pretty high end menzerna color lock. To my surprise, it didn't help much at all, so I thought maybe it needs more. I had my detail guy wash, clay, iron x, polish, seal, and wax it. Full day job. Still pretty insignificant difference. If I did that on any other vehicle I have owned I could barely slide a microfiber towel and it would shoot across the hood. I cant even slide a microfiber all the way across the hood if I try. If you run your hand across it, it's just not right. Not that slick finish that new paint should have. Anyone else have this or have any suggestions? Warranty issue maybe?
  7. I've got a sunroof and I DO have the same popping. I kept thinking an acorn or something dropping out of trees hit it, but then its happened several times with no trees around. I can live with it, but I sure would like to know what it is. The noise behind the back seat drives me crazy.
  8. I cut mine. There's a couple guys on here that have gotten them out as 1 piece, but I don't know how hard it would be. Didnt look easy so I cut it. I kept the factory system though, and don't think it would be hard to weld that 1 cut back together if needed.
  9. I finally gave in and got it on my 6.2. Very easy install. Took under 1.5 hrs by myself on the driveway. Put in 4wd and back up some ramps. Couple things though. 1. Get some exhaust hanger pliers and use some sort of lube. I used silicone spray cuz wd40 is petroleum based and will break down rubber. 2. Put the Y on the muffler prior to installing. Then you dont need a stand for the back part because you can go ahead and use the hanger. Just dont tighten the band clamp holding it on til after you have the muffler on. 3. Put the pieces that go into the tips on with the hanger before you put the pipe coming from the Y back. Again, so you wont need a stand. Another big thing because when I first installed it I was terribly disappointed. It will NOT be loud at all when you first install it. BUT, give it a couple days to break in and you'll be surprised at how loud it gets. Very little if any "drone" and it sounds mean. If you are going slow, like the 25mph limit 1.5 miles through my neighborhood, you WILL hear the DFM when it kicks in. Other than that it's rare you notice it. If you're looking for it you can occasionally, but I'm kinda sound sensitive I guess. Aggravates the crap out of me cuz I hate the DFM to begin with. Finally, don't judge by video sound clips. It really doesn't give you a realistic expectation at all.
  10. It's not good for the engine, especially lifters and valves. Plus, it makes performance exhaust sound terrible for some. I also don't like the fact that I don't have a choice on DFM. If I want to use that "feature" or the auto stop/start to supposedly save fuel mileage, that's great and I could turn that feature on. But I don't feel like it should be the default because most of the people that buy these trucks aren't buying them because they want good gas mileage. Get a V6, diesel or turbo 4 if you want mileage but leave my V8 alone.
  11. How long did it take you guys to swap out the exhaust with the cat back system?
  12. Exactly. It would also help tremendously if they'd have the adjustable seatbelts too.
  13. Looks awesome. . . and like a very expensive endeavor
