2007-2008 Chevrolet Avalanche 5.3L and 6.0L Custom Tuning

Black Bear Performance offers three different levels of custom tuning service for your 2007-2008 Chevrolet Avalanche 5.3L and 6.0L. 15-20hp gains are common out of the 5.3L variation and 6.0L engines can see a monster 40-50 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! Additional service offerings include: VATS Delete AFM Delete Torque Management Modification/Removal Tire/Gear Change Calibration Speed and Rev Limiter Increase Accommodation of Most Modifications (Internal engine modifications, superchargers, turbochargers*, upgraded transmissions, etc). All 2007+ 5.3Ls owners are strongly encouraged to use a minimum of 89 octane at all times due to compression ratio. *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.
