    2003 Manual Truck. No Turbo Flow Tables or Wastegatge Tables

    Can anyone lead me in the direction of how the turbo is controlled on an 03 truck? I do not see any controls under Airflow as in the later models. Thank you.

    Embedded control algorithms, the tables you see available on the later models doesn?t exist on the 03/04 models.

    The 03 doesn't have any electronic control over the turbo; mechanical wastegate only.

    They are one of my favorite stock turbos. I have some of those trucks making like 25psi at 1200rpm with the he341. It's unreal how fast they spool. They certainly peeter out pretty quick up top but for a tow rig they are amazing. I've managed 450+rwhp out of them.
