    First time startup with mods

    Brand new to tuning and the HP software. I am taking some courses at HP Academy, watching lots of videos on Youtube and reading as much as I can, but I am a ways off from understanding it all and need some help. I have a 2006 Trailblazer SS with a fresh rebuilt 6.0. I have added several mods including:

    Texas Speed Torquer V2 cam 232/234 .600"/.600" 112 LSA 110 ICL
    LT Headers and Cat delete
    Fuel Injector Connection - 42LB@43.5PSI MATCHED 48MM 14 14
    PCM of NC E85 sensor and Warbro fuel pump
    Stage 3 Trans rebuild
    Circle D 3200 stall converter

    I am hoping to get some guidance on what all changes I should be making before trying to start it up for the first time. I have no problem reading or watching stuff, but I am not confident enough to make the changes myself yet. What I really want is to see the changes and to understand why they are being made.

    Thank you to anyone that may be able to help me out.

    Update the tune with the correct injector data (flow rate, offsets, min pulse, ...) would be my choice for most important. Distant second would be base minimum idle airflow.
