    Default LB7 Cab and Chassis Stock file

    Hey guys,
    Does anyone have a stock file for a 2003 LB7, manual trans cab and chassis? It's a wrecker, with a single tank.

    Not sure this will even correct it, it's not the original ECM in the truck I don't believe.... said his fuel gauge doesn't work but he can make it work with his scan tool? It currently just has a file from an 89044 regular pickup in it.

    Here's the vin, thanks

    The cab and chassis tune will be for dual tanks, sounds like you need a 3500 tune file from a 3500 pickup not the cab and chassis.

    If you haven't got it yet I could get the exact one for you. I'll use my buddies lb7 ecm benchtop tune it using the MDI and gm sps per your vin read and save the ecm file and email it to you or send it via here.

    That is NOT a cab and chassis tune. The cab and chassis trucks had dual tanks, not a single due to the different width frame rails not allowing for a full size front tank.

    Look at my picture GM SPS site has two options to choose single or dual tanks. It might be cab and chassis just one with single tank not dual or visa versa
