    Wow,at least you’re getting a new motor while it’s still under warranty. 🥴👍🏻😎

    How many miles are on yours?

    I bet they end up replacing the turbo before it’s all said and done. They replaced turbo actuator and did a range of motion relearn on mine and still didn’t fix the problem. GM has had a problem with the mounting bolts on the actuator getting loose and allowing the the actuator to get out of...

    Are you referring to the rattle(like spark knock in a gas engine) or the surge? If it’s the rattle,my personal opinion (mechanic for 50 years now) is it’s just like a lean,no load,high vacuum timing period. The engines are run so lean to pass emission standards,even the diesel’s. If it is...

    Mine has always had engine clatter at light,no load acceleration. If I press on the pedal just slightly,it goes away completely. I’ve got about 4000 miles since turbo assembly was replaced and no problems. 🤞🏻the funny thing is with original turbo,engine was quiet,no exhaust noise or turbo noise...

    Got a message on dash saying that in 175 miles speed would be limited to 65 mph. Funny thing is when the code set truck was instantly down on power and would only run 53 mph with foot on the floor. I keep a scan tool in truck,so I tried clearing the engine trouble code. I was able to clear code...

    I took truck to dealer and performed the module relearn. Picked truck up and it was running great,with no hesitation. Put about 500 miles on truck and it went back into limp mode again. Took back to dealer. They said it needed an actuator and would have to order it. Got it in and replaced...

    There are several brands out there,the one I chose was”Autostop Eliminator “. Was $99.00. I have a Denali with center console. You have to remove the center console and face on center of dash to expose the back of auto stop button. The module plugs inline to the button and connecting harness...

    Yeah,I couldn’t deal with the auto stop any longer. Bought the module to disable it. Best money I spent. 👍🏻

    Yeah,throttle lag is worse,then goes from 1500-2000 jerking the truck like a two stroke hitting the power and on a dirt bike. 🤣. I’ve only put about 20 miles on it so far. I cleared the code after adding def,once the warning went away. I checked yesterday with scan tool and no codes have come...

    I recently had my 2020 Denali with 3.0 duramax in for a problem with my cruise control. They replaced several parts,and among them was the engine control module. When I got the truck back, the cruise was working,but engine performance seemed a little weird. When I take off from a dead...

    Stealth module for 3.0

    Definitely something to consider. 🤔🥴👍🏻

    Stealth module for 3.0

    I got a notice that the stealth module is being released for the 3.0. I was wondering if anyone has tried one yet? I would love to see a dyno comparison before and after. You would think if it was a significant change,they would post this info. 🤷🏻‍♂️Price looks to be around $700.00. A lot of...
