For 1996-2003 6.5 Turbo Diesel Trucks and H1 Hummer calibrations
You need to do the following:

  1.   DO NOT read the ECM for these models.
  2.   Query the computer/vehicle for VIN information.
  3.   We need the VIN (17 Characters) and the computer SOFTWARE CAL number.
  4.   We will then email your file as soon as possible for your reprogramming session.
  5.   Some older calibrations may not be supported yet, so be patient.
  6.   When you receive the file from us, it’s ready for reprogramming.
  7.   Program as you normally would !
  8.   Road test and verify the performance gains. Some models will require you to re-tension the
       wastegate for the increased boost and airflow.
