Dinan Performance Engine Software for BMW X5 4.6is E53 2002-2003

Dinan D900-46X

Product Description

Dinan Performance Engine Software releases more power by re-programming the fuel mixture and ignition timing parameters of the engine management system. The software safely raises the rev-limit, giving your BMW a broader power band and greater road speed potential in each gear. Significant gains are also achieved at part throttle, making extra power available where you spend the bulk of the time driving. The top speed governor has also been eliminated, enabling the vehicle to achieve it’s ”natural” top speed.
