I missed my chance! They were for sale locally with TPMS sensors. But the price got them scooped up too quick! I’ve seen an AT4 driving around with them though. Trying to track him down and chat! Sent from my iPhone using Tapatalk Pro

I’ve definitely encountered this. Also, in Canada, on the Acura/ Honda side, despite the US company having tech bulletins & recalls for issues, we often don’t get them right away, so despite having the problem with a clear link to the TSB, I’ve been turned away until I produce the docs myself (and even then) or spend the time arguing for it. - dealer: “we don’t have access to US tech database - they don’t share their info with us” - ok here it is. : ) Sent from my iPhone using Tapatalk Pro

I ended up going with a custom shop. Did true dual exhaust from headers to tips. X-pipe to deal with V4 sound issues. Probably acts as a resonator. Sound is very manageable, but growls at throttle and start. I almost want to get a bit more sound out of it, but that’s coming from noisy import life. I do notice a bit of drone at highway speeds though, so I’m going back to try and sort it out. It just came out much cheaper than a borla, and I expect better performance not having to share the piping. Sent from my iPhone using Tapatalk Pro

Next up is to black out the exhaust tips, and look into wheels possibly. Anyone know if we can go 10” wide with the stock tires? Most stores just show the standard 9” wide. Wonder if there is rubbing? 20” x 10” Offset -18 Eye on a set of Fuel Covert D695. Red/black Sent from my iPhone using Tapatalk Pro

New badges! Updated with some custom badges with a little Canadian signature . AT4s, removed GMC. Added 5.3 & V8. And forgot to post the custom True Dual exhaust, flowmaster cans. Sent from my iPhone using Tapatalk Pro

Quick update - I added the outcomes to the noted problems for future searchers. Also added a new issue. 6. Driver Mirror Vibration - There is quite a bit of driver mirror vibration at speed. It appears that wind is catching the mirror. This does not happen with the passenger mirror. There is so much vibration at times that the mirror is unusable for clarity, only that I have a vehicle with headlights madly dancing on the road behind me. The vibration is audible through the window that parts are contacting. * so far dealer stated the tested out several 2020 sierras and this is a similar issue. To them this was a solution. Is this the same with others on 2020 Sierras???

Thanks! The itch is well imbedded : ). Coming from my imports, I’ve basically stripped down the frame and DIY’d it back up the way I want. Lots of learning, mistakes, and triumphs. Trying to be a bit more tame on this, since it’s brand new. Sent from my iPhone using Tapatalk Pro

It really is far more than a night and day difference. It makes the stock pedal feel incredibly sluggish. Even on the city mode which is what I use. The closest analogy I can feel is going from a 250cc bike to a 1000cc. Just more go on the bottom end. Going back to stock, it’s one of those rock in your seat-c’mon let’s get going-feeling. Hard to go back. But basically just need to step on the pedal more to kick in. There is just no delay on it with the PC. Sport+ mode is just ridiculous. I could only see that being used for track racing. It’ll easily chirp tires or burnout with traction control off. City driving: As for fuel economy, I’m getting better mileage on city mode vs stock by 1-3 L/100km. And worse mileage on eco mode than stock by a similar amount (eco is most likely meant for highway not city). Testing is running through a whole tank on the mode (remembers what you picked at start up). I can say eco mode for a full tank was a test of my fortitude. Sent from my iPhone using Tapatalk Pro

Maybe I’m odd, but seems like a personal conversation to me. Realistically, if you’re out in AB, the dealer isn’t going to care much about what pricing looks like in MB. Too many variables, like number of local units available, how long they’ve sat on the lot, if they’re pulling it in from another lot, sales starvation vs high demand, yours/their negotiation skills : D I’ll shoot you a pm for what I was able to shave off the sticker price.

Worked! Thanks again. I’ll have to let the dealership know because according to them, GMC is stumped about it too. Now it makes sense! Sent from my iPhone using Tapatalk Pro

Oh my, if you are right, you’re a hero! But also still helpful regardless for chiming in! Sent from my iPhone using Tapatalk Pro

Thanks for the input! Yes this works (tried before), and as long as I have the key far enough from inside that it doesn’t think I’m locking the key inside I believe. However, I’m not looking for a work-around, I’m trying to determine if the truck is working right (I don’t think it is), it’s only a few weeks old. On top of that, when I pull my kid out of the backseat (or tools, etc), this means I then have to then open the front door again to lock all the doors, or leave it open and come back to it (or press the button three times). I know it’s seems picky, but when I buy a vehicle, I test everything out, all features, drive mostly without radio or music (except to test) to hear the vehicle and listen to its “normal”, so I can identify when something breaks, needs attention, or is not functioning the way it should.
