I have a 2017 Sierra Crew Cab 6.2L 8-speed that I'm putting a Magnuson TVS1900 on. I'll have the AFM tuned to be off. My question is whether or not just tuning the AFM out is good enough, or do I have to do the whole DOD/AFM Delete thing?

I was following this thread a while back. Just sending a reminder that we'd love to see that trans filter opened up when you feel the time is right.

4 Wheel Parts has a President's Day sale on the adjustable 5100s + free install (great deal for the fronts) + $152 alignment + tax...so $535 out the door price for me in southern CA. I can't decide whether to do this or just remove the rear block for free. My goal is to level the truck as much as I can and probably keep the stock tire size. I will not tow anything. I have a supercharger too, so maybe lowering the rear an inch and a half is better than raising the front. Is it a wise idea to remove the rear block to accomplish this level?????

Halo Lifts is also a great option. http://www.halolifts.com/GMC_c_149.html

A user named Immaculate Reflections has some used ones for sale on this site. You can also order them from MRT. Here is a link for the 2017 ones that you can start your search off of (although this set might fit your 2014). http://mrtmotorsports.net/bilstein-shock-sets/bilstein-5100-complete-set/2423830433238319/i-2304103.aspx

CLASSIC!!!

I just picked up the gas cap. At first they were going to charge me because the original service advisor wasn't there to say it was free. I explained the situation and they understood and gave it to me for free. If I had to do it all over again, I would just buy some sort of cap from Home Depot. This new cap locks, so that's a plus for some, but it also means you have to unlock it every time you fill up (another key on your key ring or floating around in the glove box). You can cut the lock off the cap if you don't want to deal with the locking feature. Here's the biggest design flaw, though. There is a tab on the cap where it touches the base of the filler neck that gets stuck under the plastic housing that surrounds the whole gas tank area. I actually had to break this tab off. So it boils down to this, if you want the locking feature, get this cap. If you just want to cover the filler area, buy something from Home Depot (some sort of soft block rubber cap made for PVC pipes).

I'll let you know how it goes. If they charge me, I'll just get some sort of cap from Home Depot for $2 or so.

It should be free while under warranty; mine was. Having a dealership order one for you without going there in person might be hard. If no one helps you with this, you can try the Buick/GMC/Cadillac dealership that I went to in Woodland Hills. I worked with Sam Macuk in the service depart. It's about a 30 mile drive from Camarillo though, might not be worth it unless you find yourself on this side of the hill one day.

Morenar, thank you for this info! I brought it to my dealership on a Saturday and they have the 2017 cap arriving by Tuesday for me. At first they were jerks about it though, saying nothing was coming up with my VIN. I pressed the issue a few times until they agreed to just open a repair order, make the order, and then close the repair order. They said the only reason they were doing it was because they had the part number. Thanks again.

This won't help with any locking issues, but there is a plastic cap that goes over the capless circle/hole/structure to keep it clean. Search "WATER DUST GAS CAP COVER 2017 2018 CHEVROLET SILVERADO CAPLESS FUEL FILL" on ebay. I'm going to see if Home Depot has a basic plastic cap like this that will fit.

I saw that too and laughed at the autocorrect. My iPhone used to autocorrect "Lardass" to "Kardashian." That was a great one! Gotta get a good seal when you're working with a genital =)...OK, so I stretched the OP a bit. On a more serious note, the 3rd brake light, XM/onstar shark fin, and seal around the windshield seem to be giving quite a few people some leak problems. I'm about to seal the shark fin with silicone or something just around the outside and the small hole in the back. Does anyone know if that's a bad idea for some odd reason? Is the small hole there for a reason?

Does anyone know if the 2017's will have the same issue, or did they use a different condenser and/or lines?

The windows look great! Can you post a pic of the 70% ceramic on the windshield?
