Thanks man. It's been great so far. My kids were amazed this morning when I was showing them how it worked on the way to school! lol Yeah, I noticed that Dokus had raised his prices. I'm pretty sure that he's still cheaper than other sellers because he offers both the module and basic programming in one package. I don't really blame him for trying to capitalize on what has been a fairly popular upgrade for shortage 2016 and earlier trucks. That's a pretty large market, but it also opens up opportunities for people like you to go out on a limb and offer similar services at a lower price point.

So I've been lurking on this thread for a few days (which is a GREAT thread, by the way) and I decided to purchase a 2.5 HMI from Dokus on eBay for $225 w/ VIN programming. I figure that since the truck had a $200 credit when I bought it for not having AA/CP, this cost me $25 plus shipping. Here's my situation: my truck is a 2016 Silverado LT without factory nav that was a part of the parts shortage and didn't come with AA/CP, but everything else appeared to be ready for AA/CP. The truck came with the updated USB ports in the center console. When I contacted Dokus, I asked if it was going to be a simple plug and play deal with the HMI and he said yes, so I decided to pull the trigger. I installed the HMI last night. It was super easy to remove the lower glove box (4 - T-15 bolts), unplug the connectors, and slide the old HMI out and reverse the process to install the new HMI. Android Auto works perfectly with my Pixel 2 XL. OK Google voice commands, steering wheel volume up/down and forward/back buttons, long press of steering wheel speak button to access Google Assistant, Maps/navigation, Google Play Music, iHeart Radio App, voice texting, and voice dialing all work perfectly. If you have a 2016 shortage vehicle and you're on the fence about doing this, DO IT. You won't be disappointed. Thanks to everyone who has contributed to this thread, especially th3magpi3, for going out and trying anything and everything for those that have pre-2016 trucks. Also, shout out to Draphty for having a similar experience to me with his 2016 shortage truck which gave me more confidence to do this. Here's a picture of the 2.0 and 2.5 HMI modules.

Looks awesome! What's your setup?

For what it's worth, I had an 08 Sierra 1500 and once after I completed changing brake pads the pedal went straight to the floor just as you described. Went to the dealership and they replaced the master cylinder and even the booster (both under warranty!!) as a precaution. Sounds like you're on the right path but I figured I'd throw in my two cents. Good luck.

Truck looks great! Any rubbing with the 285s?

This is exactly what I want to do. What is the size of the AT3's you went with?

That's too bad because mine works great. I had mine updated to the latest firmware and in the last 3 days since I got it back I haven't had any issues whatsoever. Did you know if yours was updated?

Body lift? No no no, what is this, a 1984 Toyota pickup? You're truck looks good the way it is my man. If you want it higher, spend the money on a suspension lift and new leaf springs out back.

Look at the Corsa/Volant. IMO, they have the best sound out there for both V8 and V4. They use reflective sound cancelling to quite down the V4 choppa noise and their mufflers are engineered specifically for each truck. I had a Corsa on my old 08 Sierra 5.3. They're pretty pricey but I found a killer deal for it on Amazon at the time. This time around with my 2016, I'm gonna pick up the Volant version, which is quite a bit cheaper.

http://rangetechnology.com Range sells an AFM disable module that plugs into the OBDII port. It doesn't make any changes to the computer and leaves no traces for the dealer find. I used one on my 2008 Sierra 5.3 and it worked beautifully. I just sent it in to Range to have them update the firmware to work on my 2016 Silverado 5.3. Look at their website for more info.

Alright, so after a full tank using the V8 Range, my mileage dropped from 15.0 to 14.6. And yes, for all the 'I calculate my own mileage cuz GM computers SUUUUUCK' guys, I used the DIC. To be honest, I really don't care about the mileage drop. The improvement in drivability and not having to wait for the switch from V4 to V8 is what I really wanted. Besides, not to dredge up this old argument, I didn't buy my truck for the fuel efficiency. The V8 Range works as advertised and it's a huge thumbs up from me.

I never saw an expiration date on the code. I think I saw it in a post from Jan 2013 and I just used it last week so I would say there isn't an expiration.

About a year ago, I went with EBC slotted and dimpled rotors with Greenstuff pads. The rotors are terrible. The EBC site didn't tell you that a constant metal to metal rubbing noise is normal with the rotors. When I called their customer service department they offered to replace the slotted and dimpled rotors with the standard high quality replacement EBC rotors and Yellowstuff pads FOR FREE, which I ended up doing and works well. It looks like they've revised the design on the slotted rotors so maybe noise isn't an issue anymore. Although the slotted and dimpled rotors made noise and were annoying, I can't complain about their customer service. Edit: I just realized this was a thread for rear pads and rotors. Obviously with an '08 I've got drums so my experience with EBC was on the front. Sorry for confusion...

+1 - I would always get that shudder when switching too. The truck is like night and day as far as drivability is concerned. No more waiting for V8 mode when trying to accelerate. It works just as advertised. I'm still waiting to complete this first tank of fuel before I report any MPG numbers. Late this week I would say.

I got my Range V8 today. I'm looking forward to see the mileage difference with V8 only. I understand that GM has to put AFM on their V8/auto trans motors to meet federal EPA regs but damn is AFM annoying! With a good mix of freeway driving, stop and go traffic and city driving I'm currently getting 15 mpg. I'll report back in a few days to let you all know what's up. Btw, I ordered my Range V8 on Wednesday 4/10 and received it today, Friday 4/12. Awesome. Also don't forget the GM-TRUCKS coupon code for $15 off. It's still active! ;)
