Black Bear Performance offers our traditional custom tuning service for your 1996-1997 GMC Sonoma or S15 Blazer 4.3L.

10-15hp, 15-20ft-lbs of torque gains are common out of this 4.3L powerhouse.  Combine that with improved shift patterns, response and even fuel economy in many cases and you'll have what feels like a whole new vehicle!

Additional service offerings include:

  • Speed and Rev Limiter Increase
  • Torque Management Modification/Removal
  • Tire/Gear Change Calibration
  • 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.

Traditional Tune

Our traditional tune is our custom mail-order tune that does not involve data-logging.  The tune will be built off of our past experience with similarly equipped vehicles. The tune will provide horsepower and torque increases, improved throttle response and shifting, and overall driveability.
