What tuner to go with
I have a 2003 f150 fx4 with a 5.4. Add ons are k&n clod air, air raid throttle body spacer, bbk throttle body and pullys, Gibson duel exhaust, 4:56 gears with 35" nitto trail grapplers 4-5 rough country lift. I need to know what chip to install. I would like a jet chip but I can't find a stage two. Any suggestions????? Thanks

You don't use a "chip" with OBD2, you use a programmer. You need a SCT, Edge/Gryphon, or Diablo with custom tunes with those mods.
Lose the throttle body spacer, it does nothing good for you with an EFI engine.
