I Currently Finished My Ls6 Intake Swap,but It Feels Sluggish,doesnt Feel Right Would I Need A Re Tune For This Swap-it Does Pull Hard On Top End Though.it Just Does Not Have A Good Take Off,curently Have 3.73s-do Yall Think I Should Go With 4.10 Or 4.56 Its Not My Daily Driver So It Dont Matter-i Just Want To Be Able To Launch Hard.
