I use them. Very tight squeeze when parking in my garage with wife's car. I installed the Boost Auto TASK LIGHTS ON IN DRIVE MODE. I can see the wall studs better in the dark while parking in my garage.

Don't worry about it all. I used a Range disabler on a 2021 Trail Boss w/5.3 and regularly left it parked for 5 or even 7 days because I ride my Harley every day. Put it in and don't be concerned about it.

I have used a Range Technologies DFM disabler on my 2021 and 2023 Trail Bosses. Now I am running a new style Range device on my 2025 Trail Boss w/6.2. I've never had surging or any other performance issues with my Range devices, are you sure the Range device is causing your surging at cruise speeds? Maybe unplug it and road test to verify?

Here is something i just discovered about my wireless charging pad built into my console. I have always had a lot of trouble charging my phone on the charging pad. Put the phone on the pad and it would charge for two or three seconds then the green symbol turns to yellow and phone stops charging. My phone is a Samsung Galaxy S25 Ultra. I figured out if i put my phone into the charger upside down (if your looking at the icons rotate the phone 180 degrees so its upside down) the charger works perfectly and consistently. All of a sudden i have a phone that is 100% charged every time i take it out of the charger. I believe it has to do with the position of the charging coil in the charger and the position of the battery in my S25 Ultra. Anyway I wanted to leave this tip for anyone having problems charging their Samsung phone.

Just an update on Range Technologies DFM disabler. I took mine off a 2023 Silverado w/5.3 and installed it in my 2025 w/6.2. Its working perfectly, no DFM, no auto start. I do remove it before oil changes at the dealer (I'm not going to do oil changes anymore). I did my first over the air update (OTA) with it installed at my gun club yesterday and everything went smoothly, no problems. So from here on out I think everything is OK and I'm going to leave it installed. I would recommend you install it, enjoy your truck, and just drive it. No DFM, no auto start and no need to cycle through to L9 anymore.

There you go. Give the General a chance to help you. Let us know how this works out.

Bad deal. OK here is my opinion. You can kiss your wheels, tires and whatever else goodbye. They have no trade value (or may hurt the trade a little). I would start looking around for new. Now i am in the U.S. so i will only speak to US dollars but trying to realistic, $10,000 to repair, $10,000 to $14,000 for trade (maybe more). that's $20,000 to $24,000 down. (I don't know if you still owe on the 2020). Chevrolet trucks are being offered for about $10,000 under MSRP depending on stock and engine size. I got my Trail Boss 6.2 loaded Midnight package for $10,000 off MSRP in November last year. New paint, new smell, new warranty. You know what i mean. That is in the US. I would not fix your truck, I would stick an engine in it if you decide to keep it. That's my 2 cents.

Anything over 100,000 miles is great. You definitely got a lot of use from the original ball joints.

They should add cam and lifter failures to this investigation.

Not sure if 26 3500 is the same wiring as a 25 1500 (Global B). But if it is. That subject has been covered in Modifications. Search Interior Light Modification.

I think you are behind the times. That's a lot of advice and lack of knowledge from a guy who drives a 2002 Avalanche.

I believe Range Technologies states that it does not affect your warranty, but to be honest I got a Lifetime Powertrain Warranty when I purchased my truck from my dealer. I recently went in to have my active exhaust recalibrated to ZR2 spec. (this makes the exhaust 20% louder on startup and 10 or 15% louder overall in Sport Mode). I did disconnect the disabler to ensure it did not interfere with that download/recalibration. Now I was a Master Technician and spend way too much time on this forum and other related reading so I am probably being overly cautious. I would not worry about voiding your warranty. I usually introduce myself to the Service Manager and ask those questions whenever i purchase a new vehicle. They normally are very agreeable and courteous to me when buying a new truck.

Compression test, Cylinder leak down test, then Power balance test to determine next steps. The smoke is worry some.

6.2 no doubt. Tons of power. The 2025-26 models got good crankshafts. I have used a Range Technologies DFM disabler since new. I have had a 2021 5.3 without DFM, a 2023 5.3 with DFM disabled and now the 25 6.2 with DFM disabled. Holy ****** this thing is fast! I would follow your heart. Let us know when you decide.

4000 miles. 6.2. No problems. (Using Range Technologies DFM Disabler since new).
