    You are going to need bigger injectors and fuel pump to run a turbo.

    No way stock injectors can pump enough fuel.
    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.

    yea i order ls7 injectors thinking they where just bolt on and i was wrong lq aftermarket injectors are so expensive but thanks for the input anyways, don't hurt to ask but is there is anything else that i have to change for only 6 lb like timing or deleting the mass air flow
