COBB Tuning

COBB Tuning, known by the tagline "Access The Potential" is an American company providing aftermarket automobile tuning services. Founded in 1999 by Trey Cobb at Rockwall, they are now headquartered at Austin, Texas. Besides doing vehicle modifications, they also offered customers car project consultation and building; and general maintenance plus repair.
Services and products.
They focus on European brands such as BMW and Porsche and Japanese manufacturers with the likes of Subaru, Mitsubishi, Mazda and Nissan. They are specialized in modifying mechanical components like turbo kits, exhaust system and suspension to electronic parts and ECU management. COBB hit the market strong using one of the first hand held units (Accessport) to access the cars performance potential.
AccessPORT, a handheld ECU programming device which connected to OBD-II port on cars, launched in 2004 is their most popular product because it is the first one to crack Nissan GT-R's ECU code that was said as "untuneable". They also develop a software for engine tuning, AccessTUNER which is available in two variants: "Race" and "Pro". The Pro version is available only to COBB approved shops and tuners. The enthusiast 'Race' version is available to the end user only after they pass a series of tests issued by COBB and third party organisations to deem the end user competent enough to begin editing their ECU's parameters.
The AccessPORT is commonly used to tune the Subaru WRX, and is the only tuning solution on the 2015+ models. The AccessPORT comes preloaded with tunes for various "stages" that are appropriate for different levels of modification. The AccessPORT allows for further tuning through the AccessTUNER software.
Media coverage.
In 2009, "Top Gear magazine" United Kingdom revealed that 8 out of 10 Nissan GT-R that has been modified in United States are done by COBB Tuning.
