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! ;)

This happens to me alot with my 2011 Yukon. Not so much with my 2008 Sierra. I just chalk it up to the sensitivity of the nozzle when it comes to detecting vapor. The way I get around it is to lift the nozzle handle up for the first 5 gallons or so and then I slowly rest the handle back down. I don't know if it's just me getting lucky but it seems to work well.

Just bought the V8 Range a few minutes ago and I'm excited to have it in my truck ASAP. Warranty is not an issue with me since it ended in Feb., but longevity of the drivetrain is. Now, I'm not saying the tranny or rear end will blow out if I have some of the torque management stuff removed but why take the risk. For me, all I want is the factory performance WITHOUT AFM. The V8 Range with easily give me what I want, regardless of MPG savings/loss, without spending $400 for a tuner/custom tune, or even down time from shipping off my ECU to a tuner.

I had a 2004 ECSB Silverado with the same noise. The initial fix was outlined is the TSB as possibly making the problem worse. They elongated the bolt holes on the bolt in crossmember and removed the rubberized undercoating in the places where it made contact with the frame. That fixed the slow speed pop. The Intermediate steering shaft was also a problem and was fixed without hassle.
