Black Bear Performance offers three different levels of custom tuning service for your 2001-2006 Chevrolet Tahoe 4.8L and 5.3L. We commonly see gains of 15-30hp, 15-25ft-lbs of torque, depending on fuel quality, octane and vehicle condition prior to the tune. 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: 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.
