    Evidently, they didn't expect such demand.

    Hesitation,then surge

    I'm wondering if the new ecm is learning. Are you saying you didn't have throttle lag before the repairs or that the throttle lag is way worse? How many miles have you put on the truck since the NOX high code?

    Engine Swap question.

    Anything is possible. Mechanically it should not be a problem. Anymore, I would think getting the ecm flashed over would be the main hurdle.

    New to forum…21 Sierra, Coolant Control Valve P1098 fixed

    Do you think using a clear silicone grease would keep the gearbox grease from hardening/gumming up again? While you were in that deep, did you "service" the other 2 gearboxes?

    I haven't heard if the PPE can is available or not yet. You could try their webpage.

    Decked System - Suspension Modification for weight

    No experience with the deck system, but I would wait and see what the difference in height is. Nothing wrong with a little sag. Will ride better and be a bit more level. Unless you did a level kit on the front already. It's not my money, but I would suggest bags over blocks.

    24 Duramax Fuel System Failures

    No I have not. They (gm) did some "improvements" for the '24's. Maybe the 'improvements" weren't! Are you saying your Dad's dealer has 500 of them down, or gm customers, nationwide?

    Nice, but what was the sticker price? Make sure to take your heart meds, before looking!

    Need help on oil consumption issue

    You could also have them look at Bulletin 22-NA-027 and see if your camshaft cover serial number falls into a bad design. See attached bulletin. You could inspect it yourself.

    Need help on oil consumption issue

    Welcome. Any chance you could use a different dealer? GMC, Chevy, Cadillac? It doesn't matter, they will all work on them.

    They would be in front of the cooling stack. Sounds like you don't have them.
