    Post HElp tuning gen 4 ly6 bigger injectors turbo

    Hi there im new to the forum, I was trying to see if someone can help me get started tuning my truck (new to hp tuning) , first of all my truck came with originally a gen4 4.8, i switched to ly6 6.0 , gen 4 , main mods i done to it are.
    Intake -texas speed intake
    Cammed 233/232
    Injector -80lb injectors deka
    Turbo- precision 7675
    3 bar 12592525 Map Sensor
    So first thing I wanted to do is adjust my injectors, I believe I found the data for my injectors in aacorvttes.com , I'm running a ecm38 so had to scale my injector by 50% so far it turns on but my truck is running to rich,,,i also try multiplying my stoich afr but after i did that my truck did not want to start...i also change the engine size.

    so if anyone could help i would really appreciate. What are the next steps ..

    Post the tune.

    Well just from that short log I see that one bank is super lean and the other is super rich. So something is wrong with where the o2 sensors are placed.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
