    04 Silverado 5.3 help

    Hey all , my name is Chris. As the above vehicle also has a cold air intake, throttle body spacer, shorty heads and a cat back exhaust which is an x pipe and strait pipe duals. Ok with that out of the way I was wondering if anyone has or might have a decent tune for this? I am new to all of this and I just had finished the factory e fan swap, so I had to use hp to trigger the fans. But that?s about all I know from watching yt. I definitely want to learn at the same time need help getting my good fuel mileage back lol.
    And thanks again for the help.

    Get rid of that throttle body spacer.. doesn't do anything for ya.. gains you nothing.. those are an old-school carburetor trick and does nothing for fuel injected vehicles... it can also mess up the air flow and make things worse... so get rid of that.
