CarBahn is a leading developer of BMW performance tuning software. Steve Dinan, founder of Dinan Cars built the largest BMW aftermarket company in the US. CarBahn is developing, testing and approving high performance software tunes also known as flash tunes, and products that meet Steve’s standards. In addition, Steve is combining these products with proprietary high-performance products to give you the best selections of durable street car performance equipment.

CarBahn’s Flash tunes can be installed in a few different ways. One is to have a CarBahn authorize dealer to flash your car’s computer. Another is to send your car’s computer to CarBahn to flash install the performance tune. For some models, CarBahn still sells a limited quantity of flash tuners so owners can install the tuning software without removing the car computer.
