Description
Black Bear Performance offers three different levels of custom tuning service for your 2002-2006 Chevrolet Avalanche 5.3L and 8.1L.
20-25hp, 15-20ft-lbs of torque gains are common out of the 5.3L variation and 8.1L engines can see a monster 50+ ft-lbs of torque. Combine that with improved shift patterns, towing capabilities, throttle response and even fuel economy in many cases and you’ll have what feels like a whole new vehicle!
Due to frequent issues with 8.1L vehicle sensors, we strongly recommend our AutoCal or Scan cable service with those vehicles.
Additional service offerings include:
- Speed and Rev Limiter Increase
- Efan enable
- 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.
