Product Description


BUY THE KIT AND SAVE OVER $65!


Do you want the ultimate power package for your Mustang? Well look no further, because it has arrived. American Muscle introduces the kit that will launch you into quarter mile times that you have never dreamed of possible; designed to give the best possible performance upgrade for your car, without having to empty your wallet.

Based on an idea from a AmericanMuscle.com forum user, this kit contains the SCT X3 PowerFlash Tuner, Ford Racing 4.10 Gears, and 3 quarts of Royal Purple 75w90 Synthetic Gear Oil. You will shout like He-Man once this kit is finished, saying, "I HAVE THE POWER!"

As with all of our tuners, we will need some information from you in order to get your tuner ready to go so that you can get out and play with the big boys. When ordering this kit, don't forget to include your computer code (located inside of the passenger side kick panel of the car) and all modifications that you have done to your car so that we can provide you with the most accurate and hair raising tune possible.

Want extra tunes? No problem! All you need to do is select from the drop down menu below what tunes you want to have added to your programmer! Just dont forget to tell us what you want on your tunes.

When ordering Mustang XCalibrator 3 remember to click the button below to fill out your vehicle information. Failure to do so will result in a delay in the tuning process as we need all of this information before the XCal3 can be tuned:

  • Year and Model of your car
  • Computer code (Click here to locate your code)
  • Octane Used (If not specified we automatically tune for 93+ for maximum gains, 91+ in CA)
  • Rear and Transmission
  • Stock or Modified
  • Stock/H/X-Pipe Catalytic Converters or Not
  • Mufflers or Straight-through/Glasspack Style Exhaust
  • List of all modifications
  • Two-Step Box Rev Limiter RPM Range/MPH Trigger (Add-on Option Below 1999-2004 Manual Only, Uses One Tuning Bank)
  • Valet/Friend mode lets you set the RPM Range/MPH Cap when someone else is driving your car (Requires additional tune 1999+ Only)
Recommended Additional Optional Tunes:
  • Additional Octane Levels (87+ Economy, 93+ Performance, etc)
  • 2-Step Rev Limiter (1999-2004 Manual Only)
  • Valet or Friend Mode (1999-2004 Only)
  • Nitrous Tune up to 100 Shot
  • Planned Future Modifications
NOTE: Includes one tune, add additional tunes below. Each tune is custom to your car, so this product may take a few days before it ships. Some heavily modified cars, or cars with certain aftermarket parts are not tunable with a mail order tune, and may require you to take your car and XCalibrator to a local SCT dealer to have them perform a dyno tune. End-user adjustability may vary from tune to tune. Some options may not be available onscreen at this time. Please research each setting carefully before adjusting tune as incorrect settings may cause severe engine damage!

We suggest placing SCT tuner orders separately so that it will not hold up your order. SCT orders take 3-4 business days to be custom tuned. Please keep this in mind if you need expedited shipping for an SCT order.


Kit Includes the Free USB PC Interface Cable!
Note: This gear kit is for the Ford 8.8" Rear End.
