    Does it delete the D.E.F as well

    • Graham Parminter (verified owner)

      yes, this deletes the DPF system and the Egr system.

  2. bill thornton (verified owner)

    expected more ! cant find diesel tune -transmission tune -power level -no pms adjust or delete

  3. Burnard

    not happy with results. No power or economy, can’t tell the difference from stoc
    k to extreme.. Should have went with a proven ford tuner

    • Graham Parminter (verified owner)

      I would recommend checking that the vehicle is not in a limp mode, between stock and extreme there should be a noticeable difference.

    Bought a bully dog a few years ago for my 2005 f350 powerstroke And would NOT recommend this product to anybody. Lasted only 3 months and the screen went white. No idea what tune level I’m on just been guessing and no functioning gages. Wrote to bully dog many times about this and no response. Took my money and run. Oh well lesson learned. If anyone can recommend a good product for me please let me know.

    Would this work on a 2020 f250 6.7?

    • Graham (verified owner)

      No it does not.

  7. Ben

    Would this work on 2019 f350

  8. Devon

    Are there custom tunes able to be purchased and what’s the max performance tune horsepower rating on the 17-19 Ford power stoke?

    • Graham (verified owner)

      The 40428 does not support custom tunes.
