Tune Service

Black Bear Performance offers our AutoCal custom tuning service for your 2007-2019 GMC Sierra 2500/3500 6.0L.

20-25hp gains are common with 30-35ft-lbs of torque.  Significant improvements in throttle response and shift patterns.  Combine that with improved towing capabilities and even fuel economy in many cases and you'll have what feels like a whole new vehicle!

Additional service offerings include:

  • VATS Delete
  • Torque Management Modification/Removal
  • Shift Pattern and Torque Converter Recalibration
  • Tire/Gear Change Calibration
  • Speed and Rev Limiter Increase
  • Tuning for E85
  • Accommodation of Most Modifications (Internal engine modifications, superchargers, turbochargers*, upgraded transmissions, etc).


*Due to variability in turbocharger systems, they must be evaluated by our tuner prior to committing to any services.  Additional tuning service/hardware may be required.

All tuning with our AutoCal is custom designed specifically for your vehicle, your modifications and your desired tune changes. We start off by having you collect your OEM tune file(s) as well as a scan of the vehicle's operating conditions while driving. Those items are sent in to us for diagnostic review and to build your tune files.  Assuming all is acceptable to proceed, we then provide you with your custom files built for your vehicle. Copying and flashing those files takes just a few minutes.

The Details:

  • Programming of a wide range of 1998-2019 GM vehicles;  (Full Vehicle List)
  • Large, easy to read color screen
  • On-board memory allows the storage of multiple tune files and/or countless hours of logged data
  • Multiple vehicle licensing available on a single device! Up to 600 vehicles can simultaneously be tuned by a single AutoCal device with the purchase of additional service from Black Bear Performance. No other handheld offers this flexibility.
  • Full 2007+ GM 6 and 8 speed transmission tuning support (2017+ 8 or 10 speed transmissions excluded)
  • Window's PC or laptop running Win7 or higher required.
