What light bar do you have? I’m interested in doing the same setup. Sent from my iPhone using Tapatalk

On my 2020 3500 LT HD I had the same issue and through trial and error noticed it was 100% caused by having the air recirculation turned on. As soon as I turn it off the whistling stops. I mentioned it to my dealer during my first oil change and the said they have never heard of this before. Sent from my iPhone using Tapatalk

That seems like a fair deal. Enjoy the new wheels! Sent from my iPhone using Tapatalk

In Minnesota 1 ton tabs are $120 a year. A 3/4 ton is 4-5 times that here. Easy decision for me. Sent from my iPhone using Tapatalk

It does not add any hp or torque but the added throttle response is night and day different on my duramax. Sent from my iPhone using Tapatalk

I installed the peddle commander on my 2020 3500 Duramax and wow what a difference. It really woke it up! No lag and crisp shifts through that 10 speed transmission. Sent from my iPhone using Tapatalk

I was thinking about going with these for the dash. https://www.memphiscaraudio.com/product-page/prx27 Sent from my iPhone using Tapatalk

It there much to gain by replacing the factory tweeters also? Nice write up on what you used. I installed the GM kicker amp and sub to my 2020 LT and that added a lot of thump. The factory speakers still need to be replaced though. Sent from my iPhone using Tapatalk

Has anyone come up with a good light bar setup for the 2020 Silverado HDs? I have a nice 42 inch curved rough country bar that I took off my 2018 Ram 2500 before trading it in. It looks like it would fit behind the stock grill on my 2020 Silverado 3500 LT. Anyone try this yet? Wondering if blocking any portion of the radiator is a bad idea.

I had my 14 in 4 times to try and fix this. Even had the seat rails replaced. I am sad to hear it's still an issue with the 16s. That was part of the reason I traded my 14 for a new 16. Sent from my iPhone using Tapatalk

I have also had this issue with my 2016 Sierra SLT with Bose. Anyone else with a 2016 having this issue? It seems to be intermittent.

All GM accessories are still 20% off on their website. Its offer code DEC20 http://www.gmc.com/accessories.html?s_tnt=363208:1:0 I may pick up the gm under seat storage for my crew cab since I can get it for $160. Looks like the sale runs until January 4th.

Im not sure how the sales tax works in Wisconsin i am in Minnesota. I purchased my truck at Hudson Chev in Hudson Wisconsin. I paid sales tax on the price after dealer discount. My trucks MSRP was $54,540. I got a dealer discount of $5,000 and rebates of $8,762.55 with the 20% tag lease loyalty cash $500 and another $1,000 gm rebate. That got me to $54,540 - $13,762.55 = $40,777.45 before tax title license. I think your dealer can do better. I basically got 26.3% off msrp. You should be able to get them to go 2-3k lower on the price, especially at the end of the year! Good luck on your purchase!

I noticed the same thing. I prefer CarPlay for navigation but really miss the temperature. I hope a future software upgrade will fix it. It is still head and shoulders better then the slow and sluggish head unit in my 2014 SLT.
