    I wouldn’t call it heavy surging but it is noticeable. I can’t see a change on the tach or feel it but I can hear it. If I’m in a hard pull it’s fine I only notice it at part throttle usually in 6th gear when I give it a little gas but not enough to downshift. I had to take it to the dealer to fix a couple of noises it was making and one was a loose bolt on the battery tray and they had to unhook the battery to fix it. After picking it up and driving it a couple days I think the surge is better so I might be worth a try to unhook the battery and reset the computer.

    I have a 2020 Silverado HD with the 6.6L gas and mine surges as well. I notice it more when in 6th gear and I give it just enough gas to not downshift coming up hills. Did you find a fix?
