Need Help With Performance Mods For 2003 F150 Supercharged Harley Davidson Truck

Posted in Performance Chips
  • I own a 2003 f150 Harley Davidson edition. It has a 5.4L supercharged engine. Now dont get me wrong it has plenty of power but I want a little more. I dont want to get a programmer because I have been told that they wear the engine and mainly the supercharger down alot quicker and put unwanted stress on the engine. I just want to know what performance mods I could get that wouldn’t put to big of a dent in my wallet but give me that extra power. Any suggestions will be appreciated.

      Full Exhaust System
      Cold Air Intake
      Smaller pulleys on the supercharger(cheap and make a big difference)
      Throttle Body Spacer
      Headers
      Heads
      High-Flow Cats
      Programmer really doesn’t put wear and tear on your engine or s/c. I don’t know who told you that.
      Methanol Injection-haha
      Cam
      Tune
      Rebuild the rear-end
      Shift kit if it’s an auto
      Performance Clutch for smoother and faster shifting
      Short throw shifter for faster shifts
      the list goes on forver.
      Hope you find what you’re looking for, if you need more advice feel free to message me!!
