Dinan Stage 3 Performance Engine Software - 2003-2006 BMW Z4
$199.95
Stage 3 Engine Software is for use with the Ram Air Intake Duct and High Flow Throttle Body; optimizing performance and drivability. Dinan Engine Software safely raises the rev-limit by 240 RPM, endowing your car with a broader power band and greater road speed in each gear. The software also removes the top speed governor, enabling the cars to attain their "natural" top speed. Reprogramming of the drive by wire throttle system speeds up throttle response, dramatically reducing the delayed response to throttle inputs exhibited with the stock programming.
Features:
- More Power (with ram air intake duct and throttle body): Max gains of +10 HP and +9 lb-ft TRQ
- 50 State Emissions legal; CARB EO # D-176-35
- 240 RPM rev-limit increase
- Improved throttle response
- Top speed governor removed
- Smooth and predictable power delivery
Not compatible with the Z4 2.5i (E85) from 2007-2008. Dinan Ram Air Intake Duct and Throttle Body are required in order to run the Stage 3 Performance Engine Software.
