TRIFECTA Advantage:
If your vehicle is stock, or has certain modifications which "just work" and do not require tuning, you can simply plug and play with our TRIFECTA Advantage calibration. Advantage customers receive full customer support for as long as they own their vehicle. Custom tuning is not offered at this tier, and the price reflects it. It is a great entry level option if you want to get the most potential out of your vehicle with just one mod!

  • 17 Digit Vehicle Identification Number.

    Must be exactly 17 digits, 9th digit must be 0--9 or 'X', and cannot contain characters 'I', 'O', or 'Q'.

    We recommend acquiring the VIN directly from the vehicle's VIN Plaque on the dash, or the certification label in the door jamb since insurance and service documents are sometimes incorrect.

  • Leave unchanged for no adjustment.

    Updates: You do not need to perform the GPS test again if your tire size hasn't changed since your last update. This includes if you switch gearsets.


    Larger tires will read greater than 60mph on the GPS.
    Smaller tires will read less than 60mph on the GPS.


  • Choose Single File...
    Or drag and drop your file here

    We require a photo showing the speed rating on the tire sidewall as installed on the vehicle. The speed limiter will be raised in the calibration to match the speed rating of the tire.

    This field can be updated later under 'Manage Purchases'

This woke up my truck! My 2014 GMC Sierra V6 4.3 used to be sluggish but after this I was able to make it go faster. It's not fast and the furious fast but just faster than what the factory intended to be. It's a lot more fun to drive my truck!

I also added a throttle response controller to my truck so I can control my pedal in eco mode since it tends to jump when I'm at a street light or stop sign. 

I definitely recommend these guys!
