Be the first to write a review


The Dinan Performance Engine Software safely increases turbo-boost pressure from the stock 14.0 to 18.0 psi, along with properly retuned fuel mixtures, ignition timing, and full map rescaling. In fact, over 2000 lines of code have been addressed, producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. The top speed governor is removed with Dinan's software, the B7 will be capable of achieving its natural top speed as the governor has been removed.


  • More Power (with exhaust): Max gains of +88 HP @ 6500 RPM and +139 lb-ft TRQ @ 3500 RPM
  • Improved throttle response
  • Top speed governor removed
  • Full Map Rescaling, for drivability from idle to wide open throttle and everywhere in between
  • Properly Returned Fuel Mixtures, to save you gas and protect your engine
  • Retain all BMW factory engine damage safeguards
