    6l80 new TCM

    So I ordered a new TCM. Can I just write entire or do I need to take it to someone with a tech2 first.

    2008 G8 GT

    They will need a Tech2, Candi Module, and early SPS info or a passthrough (like an MDI or GM Mongoose) and an SPS subscription.

    Is there anyone on here that can bench tune the TEHCM for me. Dealer wants me to get the car towed there after I get it put in

    Speartech Fuel Injection Systems Inc. can bench tune T43's with a fresh SPS flash matching your VIN number.
