Greetings, for sale is my Bmw proceed performance chip for n54 turbocharged engines. This performance chip unleashed the hidden power Bmw restricts from your machine. Similar to jb4 performance tuning chips, this proceedV3  unleashes about 150hp going from mild to wild. Also shares similar in dash gauge commands and install. Definitely worth every penny  delivering huge Ho gains for your vehicle. Served me well for the 2+ yrs. the unit has been used. Car was returned to factory tuning so no longer needed. Professional

Installation highly recommended. No returns on electronic devices. Please do your homework and verify you have an n54 turbo charged engine prior to bidding. Additional forums and vishnue's site include helpful details about the item/ precautions and install videos. 

No returns. Is shipping only. Thanks for looking and good luck.
