Looking for improved drivability, increased horsepower and faster acceleration? Need that extra towing power or improved shift points for the track? Or are you just tired of feeling like you've been short changed on power output due to all of the restrictions programmed into your vehicle? Let us put our experience to work for you.

Black Bear Performance offers in-person and mail order computer tuning for your GM car, truck, or SUV with a twist. Every vehicle performs differently, and we realize that a standard cookie-cutter tune or handheld programmer won't always work well for everybody. When you purchase our data-logging tuning service, we will loan you the necessary hardware and software for you to connect to your vehicle's computer and record sensor data while you drive.
