I as well suffer from the "marbles in a can" noise coming from the driver's side firewall/under foot area. It sounds like it's right down by the parking brake/door speaker (which inexplicably blew, and now sounds awful). Curious if anyone has any updates on this or things to check other than the exhaust clamps. Also, where do you all find 93 octane gas? All the stations around where I live in the Redmond, Wa area only have up to 92 octane. Cheers! Evan
UPDATE: Called in to gm/onstar customer support. After 37 transfers, IT DOES EXIST, but brand new. Currently waiting for connected car team to call back to share setup instructions. So new that it's not publicly available yet in the skills section. Will report further when hooked up. Coooool Evan Sent from my SM-G955U using Tapatalk
Yup, Amazon support can't find it either. GM swears it exists. Next stop calling into GM connected car team to get the final word. I'll report back here the results if anyone cares. And as for the password part, the other skills work by including your pin in the command. "Ex, Alexa start my truck, pin 1234" Sent from my SM-G955U using Tapatalk
Just did the same setup. 5.3 with 3.42s and just put on a level kit at 275/70/18s in bfg ta ko 2. Looks awesome! Will post a pic soon since everyone always asks about tire/level/setup pics, lol. But what I'm seeing here, is that dealers can't just reprogram the ecu to know what size tires are on so all the speedo, mileage, odo, stuff is accurate? Sent from my SM-G955U using Tapatalk

Maybe not the best word usage, but essentially, if you're engine compression is low enough, the extra cost of high octane fuel is absolutely worthless. IF the compression is high enough, the engines could actually take advantage of the higher octane. I can't seem to find what the compression is on my 5.3.
Hey all, I can't seem to reliably find the compression on my '14 5.3L. I'm trying to nail this down because I'm quite curious about the fuel debate. I know there are a lot of opinions out there regarding which octane you should use, if it's better for the engine, better for mileage, etc, etc. Well, opinions shouldn't matter here, right? Based on the compression of the motor we should be able to do some basic math and figure out if a higher octane is even being fully burned or not. Maybe I'm off here...but maybe I'm not! Weigh in! -Evan
I know this post is like 3 years old at this point, but pretty sure there is a recall out on this issue. Not sure if specifically this, but I just got an alert for my '14 that there is a recall for P/S stuff. Get it checked out if you haven't already.
That is what I was worried about. They seem a tad beastly for those housings. Thanks for the input everyone. Finding a good 5202 replacement bulb for these housings that can actually be more useful than then just lighting up the lower bumper would be rad, but alas, doesn't look to be easy.
Has anyone ever successfully crammed these bad boys into the stock rectangle fog lights for a '14 silverado? https://www.amazon.com/OPT7-Fluxbeam-Light-Bulbs-000Lms/dp/B013JCQX4W/ref=sr_1_11?s=automotive&rps=1&ie=UTF8&qid=1507596346&sr=1-11&keywords=5202+LED&refinements=p_72%3A1248861011%2Cp_85%3A2470955011 I'm looking for some fogs that can double as "driving" lights when I want. Not a full replacement, but certainly more than just a little add'l light like stock fogs provide. I like to run with running lights and fogs only a lot. Thanks for the input! E
