    Well what else is cheap and gives gains... Im planning to get headers and the URD y, a manifold spacer, and no muffler duals. (Last one for loud nascar sound)

    Bigger throttle body and fuel pump upgrade. Port/polish and ECU w/ proper tune also.

    No mufflers probably won't help.

    A quick google search will tell you more than I can through this forum.

    Basically:

    - Porting means removing material from your intake passages to make them bigger and more free flowing

    - Polishing is smoothing everything out after porting to reduce turbulence

    Bigger fuel pump on a NA truck won't help, I would work on buying a ECU once you have the exhaust. Tuning the engine after headers are installed changes a lot of stuff

    URD does ship a lot of pump/filter kits to N/A guys because their stock filter clogs up.

    If you pull out a couple stock fuel pumps and filters, you will see that it is worth it. Dyno tuning an ECU after headers is a waste of money, unless you don't plan on more mods. Wait until you install more parts.

    Just disconnecting and capping off the coolant lines to your throttle body. It's supposed to prevent heat transfer from the warm coolant to your throttle body, which lets in colder/denser air in for improved combustion. That's the theory anyway.
