Welcome to Black Bear Performance, providing custom PCM tuning for late model GM vehicles.

What We Offer

Black Bear Performance offers mail order tuning for your GM Truck or SUV with a twist.

Every vehicle performs differently and we realize that a standard cookie-cutter tune won't always work well for everybody. As a result of that realization, we provide the opportunity to loan you the necessary hardware and software for you to connect to your vehicle's computer and record sensor data while you drive. By returning that data to us, we are able to analyze it and provide you with a tuned PCM that will take into account your engine's "personality". In addition, this hardware will allow you to quickly perform the common crank relearn procedure yourself in a matter of seconds, potentially saving the cost of an hour's worth of labor from a dealer or private shop.

Black Bear Performance is also a reseller of EFILive products and a partner with EFI University. We are located in Northern Virginia and would be glad to serve your GM tuning needs.
