    Default In need of a stock LMM tune.

    Pulled file from truck to correct speedo and said invalid checksum. Corrected checksum and did full flash after speedo correction and truck now wont start and not communicating with controllers. VIN is 1GTHK93679F171324 and OS is 12628594.

    Thanks for any help.
